One of your first steps (before proposing merges) should be to determine the appropriate LNAB. After you determine the best LNAB, find (or, if necessary, create) a profile for him with that LNAB, and merge all of the other profiles to that profile.
I see that most of these profiles have "Yoakum" as the LNAB. That is very likely the name he went by in Virginia or Kentucky, but I am very sure that if he was born in Germany his birth name was not Yoakum (nor Yocum). The German records lead me to think that his LNAB was Jochem.
