Hi John, I'm knew to FindMyPast and still trying to find my way around it so wasn't aware of the Suffolk Baptism Index. Wow the info you have found on it does excite me somewhat and is intriguing.
Susan Hagar Mann (1839-) was Roberts second daughter and she did indeed marry a John Falcus Curry in 1861 I remember thinking when I first found her a few years ago, what an unusual name she had as the only Hagar I knew was a Viking in a cartoon strip. I later learned Hagar was in fact a female biblical figure in the book of Genesis. Was she named after her fathers mother and sister, her grandmother and aunt? His first daughter was named Mary Forster Mann (1835-1890) it would appear after her mother Mary Lynn and grandmother Mary Forster.
Roberts first son was called James (1837-1914), was he named after his grandfather, Roberts father?
I'm thinking like Annette it has to be the same family, it can't be just a coincidence can it?
But I need to be sure before claiming someone and the date of 1808 is troubling me. It doesn't fit with Roberts ages given in the censuses of 1841, 1851 and 1861 of 30, 40 and 50 respectively, nor the date of birth given on the seaman's ticket I found on FindMyPast of 14 October 1811. 14 October would fit though with a baptism date of 17 or 23 October. I think looking at the original document the year on the ticket might be 1810 and not 1811 as given on the transcription. That of course wouldn't help with the 1808 year unless of course there was a transcription error from the parish register to the Suffolk Baptism Index.
I hope I'm not being too picky but fear a bit more work and research to do before I can claim the find and do a few triple somersaults. I am feeling optimistic however and happy to wait a little while longer to ensure accuracy.
Thanks for your help
Pete
