The only information I have on Mary, Elizabeth, Sarah & Jane is from the IGI and the Census Records.
> JANE ARSCOTT, b. Abt. 1802; m. JOHN COLES, 18 Jul 1820, Cullompton or Clyst Honiton, Devon (Source: IGI.) >SARAH ARSCOTT, b. Abt. 1804 >ELIZABETH ARSCOTT, b. Abt. 1807 >MARY ARSCOTT, b. Abt. 1817, Clyst Honiton, Devon, England
For Mary I also have 1851 Census Records which show that she was working as a Barmaid at the Coach & Horses Inn, Clyst Honinton, Aged 34.
As to where I fit in the family tree, my name is actually Elle (put an A in the wrong place earlier on in these postings and it sort of stuck). I am Richard's great great great great grandaughter through John Arscott, Walter Arscott, Ronald Arscott and then it's my Grandfather. Are you John Arscott from the ancestryaid forum Arscotts from Devon? I may have spoken to you before...
