Hi Jim

I was writing a reply a couple of hours ago when my computer froze up

I hope I can remember what I was going to tell you!
I had a look on the IGI to check on your John HINKSMAN. Found the baptism recorded there, a submitted record, which means that an LDS church member submitted it as part of their own research. It also means you have to double check it, so I went back to Scotland's People to look at the parish registers they have online. Found the baptism, and even better, they now have a link to images of the original documents, so I downloaded the one for John - the relevant bit is attached below for you

There are no other HINKSMANs in Fife or even in the whole of Scotland. I think you will find that your John's parents were from somewhere else...possibly England although I'm not familiar enough with the name to be able to tell you where. A search throught the IGI might give you some clues. There are a couple of HINKSMANs listed on the Scotland's People wills database, but both are much later than your current enquiry.
The other thing I was going to mention is, how do you know that John HINKSMAN born 1816 in Fife is your relative? Have you traced your line back to him? It would help us to help you, if you could tell us what you've already got.
Cheers

Prue
