A bit more info...Caroline Robinson's Gardiners of Narragansett lists the Albert C. Gardiner of Jesse and Elizabeth B. (Northup) as having married Harriet Delano. The Albert C. of William T. and Nancy (Hazard) is shown as having never married in Beaman's. He is in Caroline Robinson Gardiner's book on the Hazard family but without further information. That leaves the one that was the son of Randall and Hannah (---) Gardiner if the sources are correct. I saw that a lot of people are showing on their family trees that your Albert was the son of Jesse and Elizabeth, so whether they have simply all made the same error or the Gaardiner genealogy is incorrect, I do not know.
