Don, any luck with Clara? I'm trying to figure out the same thing. Family stories say her Livingston name connects to Robert Livingston (signer of the DOI), and also that she's Jennie Jerome's first cousin (Winston Churchill's mother). Not sure where they'd fit, but possibly through the Lawrences. Also, any luck tracing the Aitkens? I've been told Andrew (b 1735 in Ayrshire) is the child of Thomas Aitken (b. 1695), but no corroboration and the line stops there.
