For possible descendants or relations of this couple , the details on the monument provide some good information to start the search into the lives of Peter and Jeanie.
Here is what I learned about the couple in addition to what is stated on the stone from some quick research on Ancestry.ca.
Rev. Peter Scott - He died in Paisley, Bruce County, Ontario . The informant was John Scott. There is no indication of a relationship to the deceased.
Peter Scott, a resident of Perth County and minister of the Gospel married Jeanie Wallace, a resident of Southampton, Ontario on 24 June 1880 in Southampton. Peter was the son of John and Beatrice Scott. Jeanie was the son of John and Janet Wallace. 
Question not answered is how did Peter and Jeanie meet? There is a Wallace family enumerated on the same page as the Scott household in Saugeen Township, Bruce County, Ontario. The Peter Scott is a carpenter in 1861 and in 1871 a student. Had he gone into preparing for the ministry? His age is in line with the Peter who is later living in Hibbert Township . The Scott household has John Wallace but the wife is Lydia. There is a daughter whose name looks more like Jessie than Jeanie, but could it be her? There is a good chance these are the correct families as other Peter Scotts found in 1861 and in 1871 aren't as good a match.
In 1881, Peter and Jeanie are living in Hibbert, Perth County. Peter is a Presbyterian minister. By 1891, the census shows the addition of a daughter Janet, aged 7 to the family. The 1901 census has Peter aged 70, Jeanie aged 59 and Janet aged 17. It gives Peter's year of immigration as 1860.If this is correct, he should appear on the 1861 census.
After Peter's death in 1908, Jeanie and daughter Janet, aged 27, are found in the 1911 census living at 23 Albert Street, Paisley. At the time of Peter's death, he was living on Albert Street in Paisley.
Jeanie died 19 February 1931 in Paisley, Ontario. Because the death registration that is available is more recent than Peter's, more information is provided. The informant of her death is Jno. Scott, nephew.
