Are they thru DNA, as there a lot of people who do not belong in MY tree.
To better explain the answer to what you are asking, you need to understand what the purpose of FamilySearch is. Following is an article with the explanation of FamilySearch. Also included is an article with how to message those who have contributed to what you see and collaborate with them.
Welcome to this "Community.FamilySearch" Forum.
I am just another 'lowly User/Patron ...
The real question is: WHAT do you mean by "... you ..."
Please be aware that ...
'FamilySearch' itself DOES NOT come up with all the Family connections.
Family connections are MADE by Users/Patrons of "Family Tree" of 'FamilySearch' from all around the World.
'No' they are NOT "All" through DNA - some might be; but, only in the latter few Years.
Question: How do you know that a lot of those People DO NOT belong in your "Ancestral" Lines?
As, you DO NOT have a 'Tree' in "Family Tree" of 'FamilySearch".
Here an old 'standby' of mine, that I have previously proffered on occasion ...
Most new (and, some old) Users/Patrons DO NOT understand the basic 'nature' and 'premise' of "Family Tree" of 'FamilySearch', when they join in.
Please let me explain ...
We do not have our OWN "Tree" in "Family Tree" of 'FamilySearch'.
We ONLY have "Branches" (ie. Ancestral" lines), that are interconnected, in this SINGLE "One" World "Tree", for all of us, that is "Family Tree" of 'FamilySearch'.
"Family Tree" of 'FamilySearch' is NOT like 'On-Line' "Websites" (eg. "Ancestry_com"; or "MyHeritage_com"; or, the like); and/or, 'standalone' personal (computer) programmes (eg, the OLD, now no longer supported, "PAF"; or, "Ancestral Quest"; or, the like).
We DO NOT have "Private"/"Personal" 'Trees' in "Family Tree" of 'FamilySearch' like other 'On-Line' "Websites"; and/or, 'standalone' personal (computer) programmes.
We do not even, own; or, manage; and, are NOT even responsible for, the "Deceased" individuals/persons in "Family Tree" of 'FamilySearch'.
And, most importantly ...
We DO NOT even, own; or, manage; and, are NOT even responsible for, Our OWN "Deceased" Ancestors/Family/Relatives in "Family Tree" of 'FamilySearch'.
"Family Tree" of 'FamilySearch' is built on a "Open Edit" Platform - hence, why any registered User/Patron can "Edit" (ie. Add, Delete; and/or, Change) ANY "Deceased" individual/person in "Family Tree" of 'FamilySearch'.
That Said ...
IF, one find individuals/person in one's "Ancestral" Lines that have the added by Other Users/Patrons; THEN, they may be correct; whereas, they may be incorrect.
It is a matter doing one's due diligence; and, investigating.
IF, they are correct; THEN, all well and good - one's "Ancestral" Lines have got bigger.
IF, they are incorrect; THEN, it is a matter of addressing/fixing the problem/issue; and, later "Collaborating with the User/Patron who hade the Error or 'wayward' "Change", advising then of such.
"Family Tree" of 'FamilySearch is all about everyone working together (reducing "Duplication") and harmoniously "Collaborating" ▬ of course, in many instances, 'much easier said, than done'.
Just my take0
[ From one of the, MANY; Many; many, Users/Patrons from ALL Around the World ... ].
Welcome to the FamilySearch community. Thank you for the time you spend asking questions.
Regarding your family Tree.
To find out regarding Family Connections.
We are attaching two knowledge articles for your review.
DNA testing has become a big part of genealogy and family history. DNA matches, sometimes referred to as cousin matches, can be the link to overcoming brick walls in family history research, help adoptees find their birth families, and lead to exciting new family history discoveries.
On FamilySearch.org, you will find a free, user-friendly resource to provide simple, beginner-level answers to common DNA questions, such as:
DNA testing does not replace traditional forms of family history research. Rather, it can complement a well-documented family tree.
Please note that FamilySearch does not endorse or recommend any commercial DNA applications for genetic genealogy. Nor does our Family Tree provide specific features to post or link DNA groups based on DNA matches.
Thank you for using this wonderful website and we wish you much success.
We do hope these knowledge articles answer your question.
Hello, @Marlene Lacy.
So, in FamilySearch Family Tree, there is no "your tree," or "my tree," just one huge Family Tree. However, we do want it to be the best-sourced and most accurate public genealogical family tree in the world -- Which is why we encourage everyone to do their very best to make sure vital information and family relationships are correct and well-documented.
DNA results may or may not match the family relationships you see in Family Tree -- because there are so many types of relationships: biological, adoptive, foster, guardian, step. These different relationships can be designated as such. Thus, a child theoretically could have any number of parental relationships.
For myself, a discovery in recent years about my grandmother's biological parents via DNA testing could very well be documented here in Family Tree, if I chose to make those links. In my grandmother's case, the DNA story is very unpleasant and sensitive in nature and I do not want those biological links to be public knowledge. I do know who her biological parents are and their profiles are in Family Tree. However, publicly, my grandmother is connected to the couple who raised her and since she was not formally adopted I set the relationship as "foster."
I hope this gives you some "food-for-thought" as you work in Family Tree.
Just an additional note: When you have questions about connections that make no sense to you often it is helpful to message the person who created that link. They may well have information that helps explain their addition.
