I have been doing a bit more digging around over the past few days and am not sure how much you know so here goes with some details
My research shows that Jason was 1 of 8 and was born in Arlington, E Sussex to Thomas and Lucy (nee Tutt) in 1842 Thomas was 1 of 11 (8 boys and 3 girls) and one of his brothers, George is my great great grandfather
Thomas and George's parents were John Gosden and Elizabeth Miller. John was 1 of 5 children born to Thomas Gosden and Anne Crowhurst (who married 13/2/1779).
It starts to get a bit sketchy but I think Thomas was 1 of 3 born to Thomas Gosden (1711-1793) and Mary Funnell (they married 2/10/1748) The other children were named Sarah and John-incidentally I think John married a Mary Tutt in 1785
I have a fair bit of info around the kids of John/Elizabeth and Thomas/Anne if you want to compare what you have but let me know if there is anything else you need. I have just literally started up again after 20 years so I may come asking for info at some stage
