I was in Stratford this summer researching the Kelly family. The Kelly's lived several farms down from the Robbs and intermarried. Elizabeth McPherson Robb (Samuel and Margaret's daughter) married my great great grandfather's brother, Thomas Kelly. When my great great grandmother Augusta Pearson Kelly died during childbirth, Patrick Kelly gave his daughter to Lizzie and Thomas to raise as their own in Wisconsin.
I have photo's of the tombstones for both Samuel Robb in Stratford, and Lizzie Robb Kelly in Wisconsin, as well as some photo's of Lizzie if you are interested.
Lizzie had three children of her own. William A. Kelly, Francis John Kelly, and Margaret Robb Kelly -who died while awhile in college in 1932.
I am happy to send the photo's if you like. Any chance you have Kelly connections?
