My 2nd great grandmother was named Sarah A Ewing at birth. Subsequent generations know her as Annie Lorena Park (Ewing-1512). I hit a brick wall with her for months but when my aunt recently sent me copies of entries in our old family bible, I saw a notation that her name at birth was Sarah A Ewing and then written in, is the notation "renamed Annie L". It does not explain why she was renamed or who chose to rename her so I don't know if it preceded her marriage or not. The dates and all the family names match. Sarah/Annie married Thomas Wesley Park (Park-1639) so the Park Family Bible may have originated with them or with her son, Rupert Edmond (Park-1638).
How in the world do I notate her name to reflect this?
~Edited to add that until recently I assumed her name was Anna and Annie was a nickname. It now appears Annie may have been the actual name.
