Hi,
Not sure if your question re rights of way is out of interest or you are attempting to claim there is a right of way on what today is private land.
You mention that a house/s built 1874 are your saying these took away a right of way?
Where on the tithe map, you supplied, is this house or houses?
The point is if on the original approx 1945 footpath map there is no right of way shown, then there is no such right.
Where I live, in approx 1850, there was an ancient footpath over 3 fields owned by wealthy land owner. He closed the footpath in order to obtain surface coal nothing could be done, when the mining ceased the footpath was never reinstated.
