In Griffiths Valuation, 1862, there is a Quinton Stevenson leasing a house, office, land from a Hugh Montgomery in Lismavallaghan, Dunaghy parish, Co. Antrim. He also is the immediate lessor (next line) and leases to a Nathaniel Morton. Next line is a William Stevenson leasing from same Hugh Montgomery.
In the 1825 Tithe Applotments, same townland, is a Robert Stephenson. I presume this is their father.
Does anyone connect these two Stevensons to a father named Robert and can tell me more about Robert?
(there is an older thread on this board with a Quinten Stevenson but I think he is a different person)
