its going to be very difficult starting with Patrick Flood if he didn’t leave with his family he should be included in Griffiths Valuation of Ireland get dates
There are mention of 116 Patrick Flood’s in Ireland at time of Griffiths Valuation, here are the quantity per county, arranged by county. I have included all four of Donegal because of the strabane railway below and changed the most likely to be associated with that railway to be in bold face, at railway

lets check out the only Co Tyrone based Patrick Flood
1858 map ref 2 in townland Somersvillestown in civil parish Urney 5 acres of land and house offices and land with ho valued at £1 pa. my guess is its over 2 miles sw of strabane
within 2 townlands from Clady and the urney road. Somerville runs through it], The railway st strabane is right beside lifford on the north sise of the mourne river A railwy map shows the strabane railway route from strababne goes south a little turning northwesterly to Letterkenny, however there is another link to via Clady to Stranorlar Co Donegalsee
https://upload.wikimedia.org/wikipedia/commons/5/59/Athlone%2C_Cavan_%26_Clara._LetterKenny_Strabane_RJD_113.jpg so this Patrick is within walking distance of two railway stations possibly called the Strabane railway Co. the actual homestead showing on a map is available on Askireland. to fine the current appearance of the site go to current google map for the junction of Rabstown Road and Bellspark road an old gate is directly opposite the junction.i think the old house plot has been retained the white house with red/darl orange tiles has been bult over it. the older map1858 shows a presbyterian meeting house in Somervilletown not Kennystown
however the Flood are more connected to the catholic church church nearest to Somersvilletown is Sion Mills I think i'm out of my comfot zone
I checked
https://www.wikitree.com/genealogy/flood and didn’t find connection for patrick
Strabane Railway from BBC “Strabane actually had a railway before Belfast - reaching the town in 1845, from Londonderry. The largest rail junction in Ireland during the first half of 20th century, Strabane catered for 4 different railway companies: Great Northern Railway (which was broad gauge) and County Donegal Railways, the Strabane and Letterkenny Railway and the line to the Victoria Road, Derry (which were all narrow gauge).” Evoking memories of Strabane railway. if Patrick was on the staff he may have been moved from tyrone to Derry Donegal or towards Belfast.
then to my astonishment I found
in the 1911 census
11 in Somervillestown (Urney, East, Tyrone)
Flood Thomas 71 [ so b b~ 1830 Male Head of Family Roman Catholic Co Tyrone Farmer Cannot read - Widower - - -surely a relative of Patrick eg brother
in the 1901 census-
2 in Summervillestown (Urney, East, Tyrone)
Flood Thomas 52 so b~1848 Male Head of Family Roman Catholic Co Tyrone Farmer Cannot read - Widower -
Flood John 70 Male Brother Roman Catholic Co Tyrone - Cannot read - Widower -
not being able to read and being employed on the railway must have been difficult. however as far as the family tree goes, 18 years difference between brothers is becoming scarce but they could be three brothers
with two of them uncles to Thomas b 1857 however if you cant read your speech memory might be limited on dates etc
https://www.familysearch.org/ark:/61903/1:1:FRV7-ZYW is the death in 1913 of a Thomas Flood reg in strabane aged 74 ie b 1839
the 1901 and 1911 census
http://www.census.nationalarchives.ie/ anyway contain Carlin living in Clady and mountfield another warmer for my thoughts
what do you think of your family connecting to Somervillestown?
