I have speculated for some time that Elizabeth Calvert was the daughter of Isaac Calvert. She fits the birth of one of his unidentified daughters. Do you have confirmation that she is identified somewhere as his daughter?
Evidence shows that Elizabeth and her husband Jacob Jones were living in Morgan County, Ohio about a mile north of Hiramsburg named after Hiram Calvert a son of Robert Calvert. The Jones family were closely related to George and Sarah (Calvert) Dye and appearred to move with them in the same time period (1830)to Boone County, Indiana. Frances (Bullock) Calvert moved to Boone County, Indiana with the Dye Family and I believe she died there and was buried in the Eagle Village Cemetery. In the 1830 Brookfield Twp, Morgan County, Ohio Census it lists a Male 90 to 100 years old and a Female 70 to 80 years old in Jacob Jones household. Isaac and Frances ?
I have pursued this line tenatively into Greene County, but I have concentrated more on the Boone County time period, and researched some of their time in Morgan County, Ohio, where the county lines meander from time to time. Would love to hear more about Isaac's family.
