Hi Peter,
Thank you for your comments. William Whiston was born 1744 and died in 1819, aged 75 in Coventry.
He married a Henrietta Rew in 1780 in Coventry but was 19 years her senior. They had no living children. In her Will of 1841 Henrietta bequeaths a gold watch to her late husband's grandson William Whiston Batt which prompted the question of a first marriage and also silver to her niece Sarah Davies.
We have established that Sarah Davies is the daughter of Anderson Davies of Chester due to Sarah's late husband John Culcheth's Will of 1811 where he mentions the late Anderson Davies and his wife E. Davies, (who I was hoping was a sister and a Whiston)
Although I never assume, I am trying to tie up the Davies family and the Whiston family but you have already told me that Anderson Davies didn't marry in the County, so I am well and truly stuck.
This is the background to the story and obviously the family dies out with the death of William Whiston, so I have no option but to go backwards from that point.
Thanks again Peter for your help.
Janice
