Hello, I am a descendent of George and Elizabeth (Felsteed) Hartley of Rio, Columbia County, Wi. George is a brother of Francis, William and Benjamin, who went to Iowa. They were 4 of 10 children born to Joseph and Anna (Curtain, Kurtin) Hartley. All children were born in Cambridgeshire, England. Most of my data is confirmed from census and birth/baptism records. My George was born March 24, 1820, at Purl's Bridge, Manea, Cambridgeshire.
George and Jane could be cousins, as the Hartley's of that area used a lot of the same given names.
If you would like more information, or make corrections, I would love to compare notes.
