Hi Claire
I'm not descended from Anne, I should have put a bracket after g.grandfather! I'm descended from John.
No I've not contacted National Archives of Scotland, I hope you get lucky there, as I'd like to know more about Charles Gilchrist's background before he joined the militia - if they have it in Scotland.
I didn't get the info myself that I have on the Fifeshire Cavalry, Bruce Gilchrist who was born in England but lives in USA, researched the info a few years ago. Do you have a copy of the book The Descendants of Charles Gilchrist and Catherine Robinson Married in Boston, Lincolnshire, compiled by Bruce Gilchrist? There are 206 Pages covering just Anne and her descendants alone up to 2004! I don't know where you live, but there is a copy of the book in Boston Library, Lincs. He also printed an addendum a couple of years after the original book with more information that he had researched or had been sent to him. I know he was collecting more information to put on a CD but he has been ill and is also aged 82 now so I'm not sure the CD will be forthcoming.
At the beginning of the book where Bruce has info about Charles and Catherine, he talks about the payroll records of the Fifeshire Cavalry which are in Kew. He has also found letters regarding the formation of the Fifeshire Cavalry that are in Kew ref WO4/152, WO4/157 p 337, WO1/1094, WO (no ref dated 27 June 1795) which are printed in the book.
I met Bruce when he came over to the UK about 2003 and took him to meet my mother so he could hear, first hand from her, about information he had found out and fill in the gaps he'd missed. He's met hundreds of Gilchrist ancestors and visited over 50 libraries as well as buying 1000s of birth, marriage and death certs. I bought lots of them relating to my family from him a few years ago. The amount of research Bruce did is absolutely staggering but what is in the book up to 2004 only took him 14 years, travelling to UK from USA and visiting 100s of Gilschrist ancestors, he has photographs, newspaper reports of births, marriages and deaths and tragic accidents such as drownings at sea, etc.
I have a copy of the book compiled by Bruce Gilchrist, so if there are any gaps in your research I can probably help out.
