If it were up to me, I would definitely enter last name as "Rubin", just leaving the "?" in the Birth Surname.
Annie and Hanna are variations on the same name. Looking at only one record does not really tell one which is the best choice to enter on the Profile - but whichever it is, the other might well be entered in the AKA Field.
On the other hand -- do not believe I have seen "Zangvill" as another version for "Solomon" - are you sure we are talking about the same couple?
Also - Barbara Richman please note -- you need to download the record from FamilySearch, and then upload it to Geni in order to provide any meaningful documentation.
Entering the URL for a record seen on a site that requires logging in does not create a document showing what you were looking at - but rather it creates a picture of the log-in page.
