Caithness gets some overdue attention

The flurry of activity on the Caithness GRAY family as a result of Bobby finding and sharing his updated info on Ann SINCLAIR nee GRAY shows that several notes to myself several years ago to investigate whether or not Catherine GRAY's sisters married x and y have been proved to be valid hunches.
We've done a lot of digging and swapping our finds over the last couple of days.
Another sister also survived well into civil registration times, living to age 93, Barbara GRAY, married James McGREGOR, lived at Baderyrie, Latheron.
That leaves the fates of sisters Elizabeth and Isobel GRAY to be determined.
For some time I'd wondered if Isobel was the one who married John SUTHERLAND, but that isn't the case. However, investigation of this did lead me to correct what I had on that family on my WorldConnect database LornaPotential, which will show these updates shortly (her parents weren't Alexander GRAY and Margaret SUTHERLAND, but David GRAY and Christian BAIN);
Newly connected surnames for my GRAY family now include: GUNN, more SINCLAIRs, MUNRO, BAIKIE, McLAREN; Places are: Thurso; Mid Clyth; Stemster; Lybster; Duffus (Moray); Charlestown (Little Dunkeld, Perthshire);
Mysteries: What happened to Mary SINCLAIR and Alexander GUNN, married 1860 Lybster, appear in 1861 census at Mid Clyth, then vanish.

Also did some work on the Tongside GRAY families, whom I'm sure do connect in somehow, if only I knew how/where: Alexander & Margaret (SUTHERLAND) GRAY, who lived next to my William & Isabella (MANSON) GRAY, as did their respective descendants over the years.

Both Rootsweb WorldConnect databases are in the process of being updated, so use these links to access them until the indexing catches up over the next 2-3 days: LornaHenderson, LornaPotential.
