Not long ago I wrote about the Axholme Ancestry web site, which seems to have some very useful information for people whose ancestors came from that part of the world. The Isle of Axholme is in north-west Lincolnshire, bordering Yorkshire and Nottinghamshire.
One of my ancestors from there, John Vause (1747-1823), married an Elizabeth Brooks in Epworth on 4 January 1780. They had four children: Richard, John, Samuel and Sarah. Elizabeth died when Sarah was a couple of months old, and Sarah herself died a few months later.
Since I first visited the site a month ago someone else has added some more information, including the probable parents of Elizabeth Brooks, Samuel and Sarah Brooks. They had a daughter Elizabeth baptised on 6 September 1745, which makes her about the right age, and since the third son and first daughter were named Samuel and Sarah respectively, it seems that Samuel and Sarah (senior) were probably her parents. So that takes another family line another generation back.
