Sorry I don't know who Sarah may be.
Edward Linsey baptised 30 Dec 1781 at South Witham was our joint 4th great grandfather. His parents were Edward and Elizabeth, I haven't found their marriage, so no surname for her.
But I do have the senior Edwards baptism 2nd Feb 1754 at South Witham, parents Henry and Elizabeth LINDSEY.
Edward (1781) was buried in Billingsborough on 13th Nov 1825 at the early age of 44. His wife Hannah Ellis went on to marry John Woodford on the same day as my 3x great grandfather married Hannah Woodford 2nd March 1829 in Billingborough.
Henry Lindsey married 13th Nov 1750 in S Witham to Elizabeth Richardson. He was baptised S Witham 31 Jan 1724 with parents Henry and Catherine, do you want to go further back?
