Dr. John KAY

I see that a john kay and his wife Catherine settled in perth county, milverton, mornington twp. Was he still practicing as a doctor or would that be his son. His son was john kay and was married to a Margaret monteith. I am doing our family tree, and hoping that I have the right place and family, so if you wouldn't mind, let me know any information you have on the family. 

I have dr. John Kay b-1807 Scotland and d-1863 apparently is buried at Roy's Cemetery, Fullerton Twp., Perth County, and Catherine miller his wife b- 1818 in Scotland, d- Dec 29 1872 and buried with her husband Dr. John Kay. They were married in Barony Lanark Scotland June 24 1832. I am looking for any information of Catherine, I know she had a sister that married my gggrandfather Robert Ferguson in Scotland, Barony, Lanark, April 8, 1832, that same year. Catherine's parents were Thomas Miller and Mary Patterson, that I know of. Any help would be greatly appreciated. Also, is there a site online where I can see the gravestone of John and Catherine. Thank you very much and I look forward to hear back from you.
