The second F may have been dropped over the years
She married James Dunn 1835-1918 England
They had the following children
Samuel F Dunn 1854
John Dunn 1863-1901
and I believe a few more
If any of these names and dated tie in with any information you have on your family tree
please reply.
John Dunn is my Great Grandfather
Emma is therefore my great great grandmother
