Sorry bedfordshireboy and Shaun...the reply that I thought I had posted to you seems to have been wiped...probably by something I did my end! Let's see if I can recall what I said. First off...thank-you both for all the time and trouble you have put into this. All the new information is very welcome and answers a lot of questions.
Shaun - I did know about Rosina's marriage to John Flynn, but not the other details. Thanks for all that. If what we found previously was correct, they had a daughter, Augusta Evelyn Flynn, born 1873, Kensington, London. We never took it further as we had so much else to look into at the time, and she wasn't a direct line.
bedfordshireboy - thank-you too, for all you have provided. We only wondered if Susan 'could have' been the mother of any of John's children a: because we didn't know that there were two Susan's involved, and John did end up marrying a Susan; b: because we have already uncovered a long past relative who had fathered several children by a household maid. It was confirmed by his will in which he left details of his bequest to them and the mother.
Going by the earlier post about Rosina's marriage...her father, John Jenks, was calling himself a 'gentleman' then too.
Thank-you again for all you have done both of you...and I hope you did not mind me including you both on the same post.
Regards, Shalena
