Dna matches Cm #’s are same as my nieces matches?
I’ve been searching for the birth parents of my grandfather David Long (adopted Shiflett) who was born in Oklahoma 1912. i manage my Nieces dna on ancestry, she had 3 matches in Oklahoma with the following cm 816, 545 and 284. These 3 people are all managed by the same person, and are all from the same community where my grandfather grew up. I know 2 of these people are the managers ex husband and daughter, the other one I think may be the husbands brother. I have spoken with the manager of this dna and she says they didn’t know who the ex husbands bio father was... but have concluded with dna that his father was someone with surname “Fine” ... so the name “Fine” and “Blockolski” shows up in some of my nieces matches trees.... so yesterday I finally get my dna results and my cm match to these 3 people are the same exact cm numbers as my nieces cm numbers to them. So I guess my question is ... does this make sense? Should we have the same exact level of cm with our matches? And does the fact that we have the same numbers matching these same 3 people help at all? I’m convinced this family has to be tied to my grandfathers burth family ... I’ve found no connection whatsoever to my maternal side. And 🤷🏻♀️I dont know🤷🏻♀️ who I’m related to on my paternal side because my fathers parents were both adopted, they had 2 children which were my father and his brother but my uncle never had children. My father says his father had another child, a daughter who was born before he and my grandmother met but that’s all he knew. @Carolyn Webber @Genetic Genealogy Research @General Questions @United States Genealogy Research @Family History Research @Midwest @Western United States Research @Southern States Family History Research

I am not much help but just to say my half sister has 1860 cm
mine is 1695 cm with our half brother
He has a close match with who we think is a half brother of 1681 cm on his paternal side
We all have the same mother but different fathers
Sounds like you are on the right track though
good luck

Thank you @Lynda Hill2 I appreciate all the help I can get at this point lol ... I just think it’s odd that she and I would have the same exact number of cm ... I thought it would for sure be different. Though, I can’t stop thinking that this fact may be a great clue as to how to figure out who these people are and how we are related ... I’m just not sure how to go about those calculations lol. She doesn’t really have a very good tree on ancestry, it’s basically a copy of mine so that won’t be helpful either ... none of these peoples names or names in their trees ring a bell for either of us. So I’m super lost! 🤣 I bet @Carolyn Webber will prob know right away lol she’s so good with all this dna stuff and calculations ... I hate numbers I must admit... it’s funny though because my most of my work history revolves around numbers 🤣

did you try looking at the DNA Painter site
https://dnapainter.com/tools/sharedcmv4 not sure it can asnswer your question but sometimes a visual works
My sister was confused by the numbers as she had a hit that we think is her paternal half brother so I sent her that site
The only other close family I have is a 2nd cousin that did the DNA test & his number was 508 cm
Maybe the segments you have with the matches help define things a bit more
Hope someone in the know replys

Which company? Is it possible that something has gotten confused, and your name has gotten attached to your niece's DNA, or that you're misinterpreting a display somehow?

Yes ty @Julia Szent-Györgyi ! Lol 🤷🏻♀️i dont know🤷🏻♀️ what I was doing wrong but I signed out and signed back in this morning and the numbers aren’t the same anymore .... however I still haven’t a clue who these people are or how we are related... I hope it’s conected to my grandfather because that would finally solve that mystery for me
but again I haven’t a clue as to how to work that because there’s no record of him being connected to anyone except his adoptive family

Ty for reminding me about that site @Lynda Hill2 😊 I did go there this morning and I only got frustrated and gave up lol. I don’t understand the Instructions and it looks like you have to know the relationship of the people for it to work or that’s what it says anyway ... I thought it was kinda the whole point of using that was to try to figure out the relationships .... I just don’t understand the instructions

I’m thinking maybe there’s some sort of calculation or better yet, a free site where I can input my numbers along with my nieces numbers and then a matches numbers and that will magically answer all my Questions 🤣

if you click on the SHARED DNA in Ancestry next to the person it gives you possible relationships
The DNAPAINTER site there is a little box near the top put your number in of the person you have a match with
It will not tell you the exact relationship but give you a few possibilities

No, DNA alone cannot tell you exact relationships.
DNA not only can't tell twins apart, it can't even tell that they exist: if my child took a DNA test on Ancestry, the site would claim with 100% certainty that the relationship to my sister is "parent-child", and MyHeritage confidently claims that my relationship to my sister is "self".
But you don't need to go to that genetic extreme: DNA can't tell whether you share about 12.5% of your genes with someone because he/she is your great-grandparent or because your parents are siblings. If the site you tested on gives ages or age ranges for your matches, you may be able to rule out some of the possibilities -- someone who's the same age as you cannot be your great-grandparent -- but generational skew can seriously mess things up. (My husband has a second cousin who is old enough to be his grandparent.)

On DNA Painter there is another tool called What Are the Odds(WATO)...a bit of a learning curve...watch some YouTube videos about it.
But first you need to find some potential couples who could be the parents. What year was your grandfather born?Look at your shared matches with these Oklahoma people and your niece...make a group of them with Ancestry’s colored dots...search both of your matches for anyone with surname Fine or Blokoski(you may have to try various spellings)...look in census records for people with those names, living in that location, of age to be parents(one surname could be his mother’s line and one the father’s)...you will have to build trees for your matches with small trees to get back to your great grandparents generation. If you find some potential parents in census records, then you must research them coming forward...find out what happened to them...who they married(likely they weren’t married to each other)...who their children were, grandchildren,etc which connect with your dna matches. It’s a big job but doable.
It’s useful to create a dna research tree in your Ancestry account that’s both private and non searchable...then you can “float” all the trees you create for your matches in this space, use the power of the Ancestry computer, and start seeing some overlap.

You are on the right track and although it might be a little more complicated given the unknown bio father of the ex-husband this is still definitely doable. I agree with Pat Nieman, definitely start by sorting your niece's (and your) DNA matches using Ancestry's colored dots with the Leeds Method https://www.danaleeds.com/the-leeds-method-with-dots/. According to the Shared cM Project on DNA Painter, there is a 95% chance that the possible relationships for 816 cMs are either great grandparent, great aunt/uncle, half aunt/uncle, first cousin, half niece/nephew, great niece/nephew or great grandchild. (Some of these can be eliminated based on age etc.) Newspapers.com and Genealogybank.com are also great resources for finding obituaries that may list surviving family members.

You might also consider downloading your raw DNA data and uploading it to some of the other sites such as MyHeritage, Family Tree DNA and LivingDNA. You may be able to find more matches with people that have taken their DNA tests with these companies.

Thank you all for your help. I will definitely work on these suggestions. I sincerely appreciate your time and effort. Thank you !

Another interesting website is gedmatch.com
Here you can find many tools that may help you narrowing down your options.
I found especially useful the One-to-One and the One-to-Many comparison tool.
They allow you to make "triangulations" so that you can focus on fewer matches.

Are any of these other programs mentioned easier for the non DNA specialists ??
Also trying to find Bio father connections it is hard with no info to go on
