While browsing in an Ontario, Canada used book store I found a 10 page Turtle family history that is marked that it was written in Toronto, Canada in 1943.
It starts with John Turtle, born in County Antrim, Ireland 1806, d 1896. It says he learned linen weaving in Belfast. He married Elizabeth Elliot, she b 1800, d.1885.
It looks like they originally immigrated to Philadelphia USA and later moved to Ontario, Canada. There are 7 children listed: Elizabeth, John, Richard, Hannah, Sammuel (sic), Marry Ann (sic), and Martha. John, Hannah and Martha were apparently blind.
If anyone is interested in a copy of this history, please let me know and I'll be glad to email a copy.
