dongibson,
My interpretation of the records is that William was mostly a farm labourer, rather than a farmer. If you look at his 1865 marriage certificate he was a servant; Mary’s birth in 1866 a labourer, Sarah’s birth in 1883, farm labourer and the 1901 census also has him as a farm labourer (not a farmer). They are very different occupations. The farmer normally owns/rents the farm, the labourer just works on it and is often provided with a cottage to live in as part of the deal. William appears to have been a farm labourer until around 1904 when he briefly had his own farm (plot 3 in Edenagon). I didn’t say that William farmed plot 1. I said that his landlord was Chambers who farmed plot 1 so I’d suspect William had a cottage on that farm. That Chambers was his landlord is shown on the census, in the house and building return. Mary Somerville also had a cottage there which again is not in the Valuation revision records. I think she was Eliza Gibson (nee Somerville)’s mother. Death certificate here. Eliza was the informant.

Labourer’s cottages were sometimes listed in Griffiths but if they were of too low a value it wasn’t worth it. I do not see William in Galbally or Edenagon before 1904 so suspect his cottage was of too low value to be listed. (And will not still be standing today. It will either have fallen down or been cleared away).
I notice that a Neville Gibson & Charlton Gibson both had farms in Galbally. Relations perhaps? It’s possible William lodged with them but as a married man with children he is more likely to have had his own cottage. William’s father was a farmer (according to the 1865 marriage) but it’s not clear to me where he lived.
So the only building linked to your William that is probably still standing is likely to be the ruin on plot 3. I agree the roads have changed over the years. That was common but there still looks to be access to plot 3 up that dead end lane. Presumably whoever farms the land today still needs access, and I think you can probably drive up it. If not you can certainly walk. Unless it’s fenced off or gated you won’t need permission, and you won’t get shot. (This is not America).
You ask where I got the information I referred to. The information about William’s cottage in 1901 is from the 1901 census. If you look at the House & building return on the census it gives you the extra information I mentioned. You can do the same thing for plot 3 in Edenagon (William’s farm). He was replaced by John McCrossan and in 1911 his family is listed.

The house & building return tells you the walls were made of stone, the roof was wood or thatch; 4 rooms in the house and 2 windows at the front. The outbuildings return tells you there was a stable, cow house, dairy, piggery, fowl house & a shed.
The Valuation Revision records (which take Griffiths forward up to 1929) are on the PRONI website. Plot 3 was still owned by John McCrossan in 1929 when the records stop. According to the PRONI wills site, John McCrossan died in 1941 and was still living in Edenagon then. Probate abstract here (again from the PRONI wills site):
McCrossan John of Edenagon Dromore county Tyrone farmer died 24 February 1941 Administration Londonderry 14 January to Annie Agnes Smith married woman. Effects £155 10s.
The 1901 census tells you that Eliza Sommerville had a sister Maggie. She appears to have marred Joseph Lambert:

They were still there in 1911:

You mentioned a family story that someone worked for the railroad. It may be a complete coincidence but I noticed these Lamberts who all worked on the railway and who might be related. (Lambert is not a common name in Tyrone. Just 20 in the 1911 census).
Probate abstract (PRONI wills site): Lambert John of Drumskinney Dromore county Tyrone retired station master died 17 March 1942 Probate Londonderry 26 January to William Thomas Lambert and Richard Lambert railway clerks. Effects £414 0s. 11d.
The will itself is not on-line but can be viewed free at PRONI.
The railway from Enniskillen to Omagh went through Galbally as you probably know and Dromore Road station, Drumskinney, was just half a mile away. So I’d be quite surprised if the retired Lambert stationmaster at Drumskinney wasn’t a relation. (Latterly in the 1940s and 1950s, there was a railcar stop in Galbally itself, where you could flag the train down if you wanted to board). The line close din 1957.

This could well be John Lambert the stationmaster in the 1911 census, then living in Co Louth but born in Tyrone:

His marriage in 1899 when he was a porter at Irvinestown station.
