1)The Senator from NH was John Langdon.References to Thomas are errors, whether made now or by Washington himself. 2)I had Thomas with last name Leavitt.I've changed it to Langdon, but I'm not totally convinced that I was wrong originally.A death record of a daughter is quite removed from the maiden name of the mother.And the death record of Mary Pottle herself could even be in error regarding her maiden name.Clearly Langdon is a "better" name than Leavitt given that John Langdon was a Signer, Senator and Governor, and if Mary had been briefly married to a Langdon, the name could've stuck. Also, if mother Mary C was a Langdon, the name could have "skipped" a generation.I have seen it before in the vitals. 3)Thomas was a Leavitt name and there was both Leavitts and Langdons in Portsmouth where Thomas was born. 4)Whereas daughter Fanny Ludington's DR says she was born in Stratham, Maine, clearly in error, one has to wonder, why Maine?Was her grandfather a Maine Leavitt? Lastly)Does anyone know why I had called him a Leavitt?
