To all who helped...firstly, it seems that Gervase Pepparday born 1774 was my friend's 5x great grandad, so we are definitely related!
I need to run by you what I understand of all the information you have shared with me.Please bear with me for being so slow, I just had to make a pictorial family tree for myself to see what I understand and what I don't! Sorry it's a long one.
Please forgive me if I get it wrong or aske the same questions again, and please forgive me if you read this on two different sites!
Ok here we go...
Gervase Pepparday (b1774) married Ellen Slack in 1804.
Firstly, Ellen Slack has an illegitimate child, Hannah Slack (b1801) who married John Clarke (m 1801) in 1822. Their children were Ann, James, John, Thomas and William. (This William is the same William found in the house of Thomas and Georgiana Pepperday in 1861)
Secondly, once married, Gervase Pepparday (b1774) and Ellen Slack have children Elizabeth (b1804) Thomas (b1807) and Joseph (b1803). I'm sure there are other children but can't get my head round the rest of them...can someone please confirm using surnames and dates of birth so I know which they are?!
Elizabeth Pepparday(b1804) marries Thomas Abbott (b1802) and they have (I think, please put me straight if I'm wrong!) two children, Gervis Abbott (b1835) and Thomas Abbott (b1840). This Thomas Abbott is the child who is brought up by the aforementioned Hannah (illegitimate daughter of Ellen Slack)and John Clarke.
Joseph Pepparday (b1803) has two children, Thomas Pepparday (b1833) and Georgiana (b1835) who are the owners of the house where William Clarke, Thomas Abbott and Gervis Abbot are residing in 1861. Thomas and Georgiana are in fact siblings, which is contrary to some information I've received so far, which suggests they may be married!
Therefore, the Abbott children Gervis and Thomas, the Pepparday children Thomas and Georgiana and The Clarke children Anne, James, John, Thomas and william are all cousins together. (NOT nephews as stated in one piece of information)
I do know there have been other people mentioned, and other scenarios.
Jenny...you mentioned that Thomas Abbott was in fact the son of a Matthew Abbott as documented in the marriage details. Does anyone know where Matthew Abbott fits into this lot?? I can't find where he goes as I have Thomas as the son of Thomas and Elizabeth as earlier mentioned.
Gardener...you quote a census from 1851 where Thomas Abbott is married to rebecca with a whole array of children... do we understand this is Thomas Abbott, the remarried father of Gervis and Thomas with his new family?
Thank you all so much for helping me to piece all this together...can you put me straight if I'm miles off? Thank you!
