I know you sent your mail at the beginning of the century so this report is rather late but no matter. I have only just seen it!
I have been researching my family ancestry and my great grand mother was Sundenia Biggs formerly, Sundenia Ashley.
On the marriage certificate, Felix Fred Biggs married Sundenia Ashley in 1860. Felix was a widower. The witnesses were; Jacob Ashley and Marianne Ashley. Sundenia's father was Richard Ashley. When tracing Richard Ashley,Jacob Ashley
and Marianne Ashley,they appear only on the 1851 census.After that they seem to have disappeared on the 1861 census. Only months after the wedding!
I am assuming that this family has some connection with the one you have mentioned but the names Sundenia,Ashley and Biggs etc.is too much of a coincidence not to have some significance. I would be interested to know what you think.
