Thomas & Sarah Ann McQuay witnessed the marriage of Robert Shear & Lydia Hartrick in Pickering Twp, Ontario 29 Mar 1864. Thomas may have been in Pickering Twp, a farmer, in 1846. He may also have been in Proton Twp, Grey County, in 1865. Perhaps it is he who is buried in Oshawa Union cemetery in Whitby, Ontario. I would be glad to hear from anyone connected to the McQuay family.
