Hello
William Sully age 27 and Mary Jane Grealy age 20 were married in Blaketown on Dec. 22 1894.
Here is the link to that provincial marriage registration found on familysearch.org. They are #2 on the page

Not mentioned in your post is a daughter Elizabeth...born Oct. 1896. She is on line #23 in the link below

Both William's marriage reg. and his daughter's birth reg. list Old Shop as his place of residence. That would be in Trinity Bay...Upper Trinity South. The 1894 directory of Old Shop has 2 Sulley entries...William of John and Joseph of John. Hope this gives you a direction to search and I'm not muddying the waters.
