Your sister can see and look at the "Deceased" individuals/persons in "Family Tree" of "FamilySearch".
The ONLY individuals/persons that your sister will NOT be able to see, is the "Living" individuals/persons that you "Created", that reside in "Family Tree" of "FamilySearch", in your "Private Spaces".
If your sister is NOT a "Registered" User/Patron of "FamilySearch", all she has to do is register - it is FREE.
And, in relation to sending messages to each other, once your sister is a "Registered" User/Patron of "FamilySearch", you will both be able to 'Message' each other through "User Messaging" of "FamilySearch".
That said ...
We do not have our OWN "Tree" in "Family Tree" of "FamilySearch".
We ONLY have "Branches", 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 "Ancestry_com" or the like.
We DO NOT have "Private"/"Personal" 'Trees' in "Family Tree" of "FamilySearch" like other "Web" Sites; and/or, 'standalone' personal programmes.
We do not even, own; or, manage; and, are NOT even responsible for, the "Deceased" individuals/person 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".
You can certainly "Merge"/"Combine" any "Deceased" individual/person in "Family Tree" of "FamilySearch" with another "Deceased" individual/person in "Family Tree" of "FamilySearch", regardless of who the User/Patron was that initially created those "Deceased" individuals/persons; as, they DO NOT reside with the User/Patron who initially created them - they are "Public".
If fact, you can ONLY see "Deceased" individual/person in "Family Tree" of "FamilySearch"; except, with this 'rider', that you can ALSO only see "Living" individual/person in "Family Tree" of "FamilySearch" that YOU created; as, they reside in your "Private Spaces".
No other User/Patron can see ANY "Living" individuals/persons that were created by another User/Patron; as, they ONLY reside in the "Private Spaces" of the User/Patron who created them.
We CANNOT even see the ACTUAL Record in "Family Tree" of "FamilySearchc" of our IMMEDIATE Family (eg. Spouse; Children; Parents; Siblings; ETC; Etc; etc) if they are "Living"; and, they have their own "FamilySearch" Account.
Of course, you can create your "Living" Family members; and, record them in "Family Tree" of "FamilySearch"; but, they will ONLY be seen by you:
- You cannot "Share" them with any other User/Patron.
- You cannot "Merge"/'Combine" them with any other "Living" individual/person residing in the "Private Spaces" of another User//Patron.
There is CURRENTLY no mechanism in "Family Tree" of "FamilySearch" for Users/Patrons, to "Share"; or, as you suggest, "give permission" to "Share", the "Living" individuals/persons in their own "Private Spaces" with/between other/another User/Patron.
There are a myriad of "Privacy" Laws within the many various Countries and Unions throughout the World - it is a nightmare to negotiate.
"Family Tree" of "FamilySearch" is used in many Countries and Unions throughout the World; and, as such, must adhere to the myriad of "Privacy" Laws throughout the World.
Hence, "Privacy" is one of the reasons that we cannot "Share" the "Living" individuals/persons in our own "Private Spaces" - it is NOT the ONLY reason; but, certainly has a bearing on the matter.
Another factor is that such would have to be 'Coded'/'Programmed' into the Programme that is "Family Tree" of "FamilySearch".
'Yes', these "Living" individuals/person in "Family Tree" of "FamilySearch" WILL, in fact, in many (most) cases will be "Duplicated" - unfortunately a necessary situation that currently cannot be avoided.
I know that there are "Duplicates" of the "Living" ME - at least, one for my Wife and each of our Children, not to mention my other ("Living") extended Family members.
Here is a good place to start, with how things work in "Family Tree" of "FamilySearch" (and, other programmes as well):
Introducing The Family History Guide
The Family History Guide
I hope this helps, to put things into perspective ...
Please DO NOT follow @X24mom X24mom's suggestion.
NEVER, EVER, give your 'UserID'; or, 'Password', to anyone, NOT even a direct Family member.
That is very BAD advice.
Generally, it is not good advice - it is practical advice - but I would never do it, for example, for work - and that's because of security concerns. Here, I am talking about a Family Tree that I clearly intend to share with my sister who is in the tree, so it's a little different situation. But, yes, as a general rule, sharing login/PW is not recommended ever. We've been trying things on the site - like Relationship Viewing - but none of that seems to work.
I am sorry to have upset you ...
That is NOT a matter of opinion.
That is a matter of what one agrees to when one "Registers" to be a "User" of "FamilySearch":
You are responsible for maintaining the confidentiality of your sign-in name and password.
Just because other people do it, does not make it right/acceptable.
Parents working with their Children, is another matter; and, does not relate to this situation; as, the Parents are LEGALLY responsible for their Children, until the come of age.
Siblings on the other hand, are another matter; and, are not the same as that in the Parent/Child scenario.
So, to say that such was "... very BAD advice ...", in not 'harsh'; but, correct.
Although you were well meaning, your solution was misguided; and, something that is best not proffered, in a "Public" Forum.
Keeping one's "UserID" and "Password" PRIVATE and CONFIDENTIAL is fundamental in ALL 'Computer' Access situations, right across everything.
Again, I am sorry to have upset you.
@VictoriaKanrek VictoriaKanrek just give her your log in info and password
Well I think that’s matter of opinion. Lots of people share their info for different sites for different reasons. Perfect example Is I’m currently logging in to all my kids google classroom accountants to check their assignments, these are their accounts not mine. I’ve shared my info with folks for different reasons. So for you to say it’s “bad” advice I think is a little harsh, she was looking for a solution and I gave her one, it’s up to her weather or not she’s comfortable doing that.
I’m not at all sure what this is or how it’s used, the description makes it sound like what you may be looking for but I’m not sure or clear about exactly what this is or how to use it. 🤣 but this is the closest thing I could find in relation to your question. You can find this by going into your FS account settings on the main familysearch.org site .... ok it won’t let me post my ss ... says “file is no longer available”? But anyway if you go into account settings and scroll down you’ll see a “helper number” and “what’s this” highlighted in blue
Thank you @Brett . 😊im not upset at all🤗 you are clearly correct. I should have phrased my response differently (lol I kinda knew I was gonna catch heat by posting that as option in the first place 🤣).
