I may have some info but I am trying to figure out the dates in your message. According to what you posted Walter Palmer Gardiner was born in 1923 but married in 1911? I found Issac in the 1880 and 1900 census - in one Nellie was called Ella and in another she was called Ellen F. There are no children with them in either census. The 1900 census indicated there were no children, either living or dead. I think Nellie would have been too old to have children with Walter Gardiner as she would have been 55 when they married. I know someone else working on this particular branch of the Gardiner family. My grandmother was a Gardiner but so far I have not found the connection to this Gardiner line. My paternal grandmother's uncle, George Horace Hall, married Ida May Gardiner who does come from the Pardon T, Walter P clan but I've never been able to get very far with it. My primary Gardiner line goes from George and Herodias down to Samuel Joseph Gardiner and Mary A. Crandall, my great grandparents.
