As I've read the help pages on names I see that the LNAB should match the records, as written in the day. And, the current last name should reflect what the person used in their life. And, other last names are for other names they were known by, other names used, etc.
My question is: if the person was born with one last name and used it through their life, but we know them as a different name today, should the commonly used name (that we use today) be in the current last name field or the other last name field?
For example, a man is born John Smythe. In the parish archives, his father was a Smythe and his christening record was Smythe.
But, a generation or two later, all of his descendants use the name Smith. Would we call him:
LNAB Smythe & current last name Smith, or
LNAB Smythe, current last name Smythe, and other last name Smith, or
if Smth wasn't used in that era, leave Smith out altogether?
thanks in advance for your replies
