Hi again Jim,
I've read all your various threads on this family.
I mentioned the HINKSMANs in the Birmingham area (who go back into the 1700s) only in passing. But, even so, if I were you I would not disregard them totally given that you don't seem to be able to trace, (with any reliability), your HINKSMANs back past John HINKSMAN b 1816 in Dysart, son of William HINKSMAN & Janet DAVIDSON. Everything else seems to be family folklore which may, or may well not, be reliable. And this means that you do not know with any remote degree of certainty what happened before 1816. So it's necessary to keep a completely open mind.
To digress for a moment, my children have the very rare Scots name LOCHTIE/LOCHTY (and, in one branch, LOUGHTY) in their ancestry - the name can be found in the early 1600s in Aberdour Fife (recorded in Dunfermline records from Aberdour - with very common Scots given names like Robert and John and Janet, etc) though this cannot be joined to the first subsequent appearances of the name in the late 1600s because of gaps in the records. LOCHTIE folklore (from a branch which seems to have split off ca 1700) is that the name came from a 'Scandinavian' seaman who married a local girl in Aberdour, Fife in the late 1500s and LOCHTIE is what the locals made of his name or place of origin. Who knows!!! The Finnish name/place of LAHTI has been suggested as the origin - again, who knows!! I feel sure we'll never know one way or another.
However, if I were you, I'd certainly check out the pre-1855 Fife Deaths CD, and the pre-1855 Fife Monumental Inscriptions booklets for all the names (including spelling variants) of interest to you (especially for the reputed Kirkcaldy MI for a HINKSMAN which you have mentioned). I'd also be searching far and wide in the 1841 census for the HINKSMANs (however spelled - though the loss of Ceres certainly doesn't help) and the DAVIDSONs and the HUTCHINSONs (though David the fisherman in St Andrews in 1841 on FreeCEN seems quite likely).
All the best,
JAP
