Thanks Karren,
Helping research for an 80 yr old lady. The couple (her parents) did marry 8 yrs later, she also had other siblings prior to the marriage. Think that he fathered them all, but was reluctant to marry, or there were probs with one being Cathlolic and one Church of England.
I have suggested she tries to trace her baptism to see if it gives anymore info. Her mother secretly also had her christened in the Catholic Church so there could be two records.
Have done quite well on the tree, both sides, she is very pleased although suprised her full length birth cert had no father, and that they married much later, also the possibility that this may not be her true paternal line.

Some things we will never get answers, such is family history!
