Well I have lots of Abrahams in my tree, 7 to be precise. the earliest is Abraham b 1793, Bridport, then 1826 again in Bridport, then c 1845 in Bridport,another in 1868 born in Mitcham, Surrey, his son c1894 again born in Mitcham. finally an Abraham b 1878 in Bridport.
The family were orginally from Bridport in Devon, but my branch moved to Mitcham at some point prior to 1865. which in those time was the other side of the world. well it was Abraham Ackerman c1845 who moved and married a Ann Hayward b 1845 in 1865 at St. John the Baptist Church in Mitcham. the couple had 13 children - they were very busy in those days.
let me know if there are any links or rings any bell with your research.
