Hi Ann
I know her parents are not on M.C. in 1818, but are they not on her D.C. ?
There does not appear to be a B.C. , looked at all Esther's born 1790-1805 on the IOM for a possible match. Also looked at all Mylrea,s born same period. Also looked for all Mylrea's with father Edward or mother Christian, but still no clues.
Assume Esther in Lancashire 1851 aged 52 , born IOM , there born circa 1799, is that correct ? Did they have any more children after they left the Island ?
Cheers
