It can be found here:http://www.fultonhistory.com/Fulton.htmlhttp://www.fultonhistory.com/Fulton.html-Search "John Rollison" in quotes and you will find the entire obit, which is rather lengthy.Here is an excerpt:
".. John Rollison was born in Edinburg, Scotland, 67 years ago.When a young man he came with his family to America and located in St. Catharines about the year 1860.He occupied various positions of trust and finally received the appointment as City Clerk on November 2, 1868... Mr. Rollison was a relative of Mrs. A. Calkins of North Tonawanda and was quite well known in the Tonawandas."
There was a Rollison family in Edinburgh in 1851 but none with John:

I found no Rawlinson families in that area, however.Hope this helps.Annie
