I wrote a book on the Scotish lines 1778-1878 a few years ago. Amazon have details under if you search under my name Guy A.S. Wingate. I've got more info now. I've been tracing Wingates since early 1980s so I've been on the trails a while. So far found branches in US, South Africa and Australia. You might be a new branch. Places to look are Scottish Genealogy Society, and books published end 1980s and early 1990s listing thousands of names of interested family historian with an huge index of names they aresearching. I'll dig out details. My e-mail is firstname.lastname@example.org
. Look forward to hearing from you.
