i Have somehow made two different accounts on here and I need to combine them into one. They both have lots of hard work done on them so please help me
Unfortunately there is not a functionality to merge two different logins for FamilySearch.
You may consider deleting the less used, knowing that you will lose some of the information you have added.
Perhaps you can just keep both accounts and know that the information is there if you need it.
Sorry I do not have better news.
Here is the knowledge article that talks about deleting a FamilySearch Account.
