Is Tom short for anything?
Yes. Tom is a nickname in most old records, and it usually points to Thomas. No other formal name claims it in the records we track. Expect it in American and British records, mostly 1500s-1900s. A record that says Tom and a record that says Thomas can easily be the same person, so search both names before you rule anyone out.
