Another thing about house numbers in a census - there were fewer households on 1911 census. A member of my family was from Glan. The numbers for their house were different on 1901 and 1911 census. They hadn't moved house. Some families had moved away or people had died so there were fewer households in the census collector's round.
There is a map to accompany Griffith's Valuation. You can enlarge it to see individual land holdings and houses.
Have you traced your ancestors back before the 1901 census to try to work out who were likely to have been tenants in 1850's when Griffith's Valuation was done? Not easy with names Horan and Moran.
I began a thread on here a couple of years ago about a Horan and a Moran from Kilmovee. You can find it by doing a search for either surname on the message board and selecting Mayo for county. We looked at a few Horan and Moran families. A descendent of one replied.
I joined Kilmovee Genealogy group recently and found a distant relative of my great-grandma. There are people in the group who live in or near Kilmovee.
There are Horans and Morans from Kilmovee in Rossendale, Lancashire, England. Some have married each other.
