10 years looking for Ann Woodman, whose illegitimate son George was baptised in 1785 in Little Sodbury, Gloucestershire, but with nothing to go on but a name, I'm probably not going to find her.
George went on to marry and have at least 2 sons (there's possibly a third, and others), George and James Martin. When George junior marries he gives his name as George Martin Woodman, son of George Martin Woodman. I did wonder if that might have been a clue to the elder George's father, but so far no sign of a marriage between Ann and a Mr Martin.
And about the same length of time looking for James' wife Eliza (nee Mathews). Fathers name left blank on the marriage certificate (James fathers details were also missing for some reason). Birthplace given on the census variously as Purton Wiltshire (possibly Porton, Wilts), Not Known and Wapley and Codrington, Glos. The 1841 census was taken after James and Eliza married, so she's not the one with father Isaac in Purton. I'm probably more likely to track down Eliza than Ann, but they are a struggle.
Thanks for listening!
