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'.
That said ...
In you case, it is not so much about "collaboration" ...
As you are ALL "Living" Users/Patrons ...
You; and, the other Users/Patrons (extended family members), WILL have to "Added" SEPERATELY (and, 'Yes' as DUPLICATES) the "Living" individuals/persons that connect/link you together in your respective 'FamilySearch' Accounts ...
Basically, you and your extended Family members have to "Build" a "Bridge" of the "Living" individuals/persons that connect/link you together in your respective 'FamilySearch' Accounts ...
Once, you have built that bridge; then, when you come to your FIRST Common "Deceased" Ancestors, your various "Ancestral" lines will connect/link together into one ...
Let me explain ...
[ Please bear with me ... I am very verbose ... that is my 'Style' ... ]
"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'.
"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" individuals/persons 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 'FamilySearch' 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, "give permission" to "Share", the "Living" individuals/persons in their own "Private Spaces" with/between other/another User(s)/Patron(s).
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 are some "Knowledge Articles" in 'FamilySearch' in regard to "Private Spaces" and "Living" individuals/persons:

Who can see my living relatives in Family Tree?
Here is a good place to start, with how things work in "Family Tree" of 'FamilySearch' (and, other programmes as well):

I hope this helps.
Thank you, Brett. This makes everything clearer. I feel much better, knowing why all my efforts to coordinate with my mom failed.
@StephanieEastwood1 StephanieEastwood1 That's awesome that family members are joining FamilySearch! There are lots of different ways family members can collaborate/coordinate with each other. For instance, I really enjoy research and my sister really loves photography. She preserves and shares the photos on FamilySearch. I do what I really love. Sometimes each family member will do both research and memories for example, while focusing on different ancestral lines. Then come together when you need help on a specific deceased person or family. Sometimes it helps to work together on some projects like creating a book or piecing together a family that may be complicated. So glad you still have your mom to work with. She is a valuable source for you as well as any other older relative! Wish I would have asked my mom and dad more questions......
Enjoy the journey!
