Many thanks for your reply. I am aware of the memorial on FindAGrave that you provided since the person that developed the information is my wife's cousin. He has done a lot of research but there is one piece that I believe does not make sense. He does have a memorial in Paisley for Mary (nee. Norton) Stait but there is no actual gravestone nor burial record to support it.
According to the timeline that I am pursuing, Mary died around 1852 while the family was in residence in the Hamilton area. William remarried in about 1853 and had 4 more children before moiving to Paisley sometime after his census record in 1861, still in Hamilton.
For Mary to be buried in Paisley, William would have had to take her remains with him when he moved to Paisley, some 10 years after her death. I find this highly unlikely. Therefore, she was more likely buried near Hamilton in 1852 +/_.
One of the things I enjoy about Geneaolgy is trying to solve some of the "mysteries" that seem to always be present.
Thanks again for your digging.
