A bit more on Samuel Douglas, as well as appearing in the Griffith Valuation of 1858, at that time farming 25 acres, Samuel also appears in a rental records from, 1850 and 1851. Plot 2 Carrowhugh farming 14 acres, £12 12s per year, tenant year to year.
There dosen't appear to be any Douglas families farming in Carrowhugh or any other townland in lower Moville at the time of the Tithe records recorded of 1828, the family at this time seems to have been living in the parish of Moville Upper.
Don't see any burial records for Samuel or any children's marriage records. I suspect he was probably an elder brother of James Douglas and a bachelor, his tenancy was probably taken over by James after his death, and passed from him to his sons, John and James
