Hello all. I'm seeking any information on the below people and families to help progress my research. This stems from my research into a Patrick McMahon who was born ca. 1862. Patrick the son later immigrated to New York City where he married, had a family, and died. His parents were likely born in the 1820s-1840s timeframe, but I have not yet been successful in finding any records in Monaghan (or elsewhere in Ireland) relating to them, additonal children born to them, names of their siblings/parents, etc.
Cornacarrow McMahons (1901 Irish Census)
Possible match for the parents, but none of these first three people seem to appear on the 1911 Census:
Patrick McMahon b. 1826
Alice McMahon (wife) b. 1831
Alice McMahon (sister) b. 1816
Residents of home next door (likely their relatives):
Thomas McMahon b. 1826
Mary McMahon b. 1843 (wife)
Various children (Thomas, Mary Ellen, Kate Anne) and a grandson (Patrick Joseph Lambe)
