Yes, some of them. John Gartshore (c1690-1752) married Susanna or Ann Howie, who has to be related to my Howies of Meikle Drumgray. Their son Robert Gartshore married Mary Mochrie, whose mother was my 4th-great-grand-aunt Mary Waddell of Stanrigg, so I am related once and probably connected at least twice. I'm in touch with other Gartshore researchers, and have quite a lot of information about them.
