Is Tamsin short for anything?
Yes. Tamsin is a nickname in most old records, and it usually points to Thomasina. No other formal name claims it in the records we track. Expect it in English and Welsh records, mostly 1600s-1900s. A record that says Tamsin and a record that says Thomasina can easily be the same person, so search both names before you rule anyone out.
