I have come to a stop on my family tree. My mother has no trace of a birth cert..? We know her mother was married (husbands name not known) and found he was a bigamist. My grandmother then was sent away had my mum and she was brought up in a convent (don't know where) by a dutch nun..from age 5 she was then brought up by her step fathers parents in Norfolk...My nan was Irish as was her 1st husband but I can find no records of her..she did change her name from Julia Anne to Sheila although not sure when or why..? Her surname was McDonnell and her 2nd married name was CUTTING..?
