So happy to hear from you Mary! You have some that I don't and I have some that you don't. Where our info meets, I have the same.
Nancy was the full sister of my ancestor, James Slack, born Sept. 10, 1824. James married Abigail Wooley, Oct. 11, 1848. They emigrated to Michigan in 1867-1868. I can give you their children, if you want it.
They also had half-siblings:
Ezekiel Chambers, born May 27, 1816 in Oakland, Ont.; died Sept 27, 1898 in Ubly, Michigan
Hannah Chambers, born in 1818 and died in 1905. Hannah married William Carrol. Their son, Ezekiel, married Melissa Doxsie. Hannah and William lived in Huron County, Ont.
Phebe Treadwell, born Jan. 25, 1831. She married Samuel Emigh and died by 1880.
Euphemia Treadwell, born June 4, 1833. She married Theodore Conklin, May 31, 1857 at Almont, Lapeer Co., Michigan.
Susanna Treadwell, born Jan. 1, 1835. She married David Dopp in Millington, Tuscola Co., Michigan. She had died by the 1860 census.
In addition, there are step-siblings of Nathen Treadwell's first marriage. I can give you those.
We have had no luck tracing Nancy's parents. We know that they were a John Slack and Hopey Chambers. We do not know if Chambers was her maiden name as well as the name of her first husband, James Chambers.
Hopey Chambers has a traditional birthdate of March 29, 1789. She is recorded as Mrs. N. Treadwell in the 1852 census as age 53. So perhaps the year should be 1798or 1799?
Nathen Treadwell, Hope's third husband, married Mary Tuttle, both of Norwich, on Nov. 17, 1853. So hope died 1852-1853. Rev. Silvanus Nichols officiated and the witness was George Tice. Tradition has James Slack born in Townsend Township 'among the Tice's'.
I can give you children of Nancy's siblings if you would want that.
Here is what I have further on Nancy and Adam Doxey/Doxsie
Witnesses to John and Nancy's wedding were Franklin W. Earl and William Amy (Emigh?). They were married by Rev. Silvanus Nichols. Adam died in Tillsonburg (in North Norwich, or very close to it) Sept. 24, 1900.
In the Burgessville Cemetery, there is a burial for:
___________, daughter of Adam and Nancy Doxsie/ who died July 22, 1870/ aged 22 years, 19 days. I calculate that she would have been born July 3, 1848---unless it should read: aged 12 years, 19 days. Then it would seem to be the missing Cynthia. 1848 makes the birth very much before the marriage.
There is also a burial for:
In Memory of David A. /son of Adam and Nancy Doxsie/ died Nov. 21, 1892/ aged 25 years, 6 months, 23 days. (I calculate a birthdate of April 29, 1867
We would love to connect John Slack to his family. We believe that he is a member of the Slaght family from New Jersey, but have not been able to verify that. We also would love to find Hope/Hopey's family. Both John and Hopey are reported traditionally as being born in Ontario--Oxford or Townsend Township, Norfolk.
I hope this will fill in some gaps for you. Please Email me if you want children of the half-siblings and brother James.
