Clever pick up Lizzie
It doesn't say on the marriage to James Dundsen but it looks like she was.
John Bavis married Ann Taylor 9.3.1796 Steventon.
John buried 19.8.1803
Children- Moses 4.9.1796,Aaron 30.9.1798-27.3.1831,Dina 21.9.1800 and Jeremiah 2.1.1803-25.12.1803.
Possible bapt at Wantage
Ann Stroud Taylor 20.8./bapt 27.9.1775 d of Richard and Mary Taylor.
Death Cert for James does put him a bit older but the age is down to Sarah Bunce so maybe she wasn't sure.
James Dunsden 23.6.1843 age 70 lab Steventon ashmatic inf Sarah Bunce.
So birth 1773 which doesn't fit with the census or burial.70 abit too much of a round number for me.
But you were right Ann was a widow.
