One of our family plots at Elmwood Cemetery, Detroit, MI, contains the grave of William Adair. He shares a large-ish monument that reads: BLAIN- GRAY- ADAIR. My research shows that this Adair was a MI State Senator in the 1860s, and a Nurseryman and Horticulturist. Likely a cousin to Alexander Blain in same family plot. Born either Quebec or Scotland. Burial date late 1890s/early 1900s. Possibly a nephew of Janet Adair, mother of Alex Blain.
