Hi, dont know if you have advanced any since last post but I have some information that might help. John Davidson was my Gt Gt Gt Grandfather. He was married to Elizabeth Booth on the 26/12/1815 in Monquhitter Aberdeenshire. John was born in Peterhead in 1795 Lived in 21 North St Peterhead and died on the 18/11/1869. Elizabeth was born in 1793 in Mill of Allen Monquihitter and died 30/5/1870. I have a copy of their marraige from the parish registar in Peterhead if you are interested.
Hope this helps
Dave
