Add person with ID number as spouse to my sister
My brother-in-law has his own familysearch account and his id number. I want to add him as my sister's spouse on my account. It is not accepting him. I may have made an error by deleting him on my account, and then trying to add him with his ID.
Now neither id number for him will add as my sister's spouse and I don't want to create a new person.
Does anyone have any ideas for solutions?
