I would love to hear your father's story about how he received his middle name! It may help me identify John Wisnom's (father of Jane Wisnom) father. My maiden name is Wisnom. My ancestor immigrated from Ballycarry in 1868 to San Mateo, California, USA.
This is what I have on John Wisnom: John Wisnom (b. 1807) leased land in the NE Division in 1862 at the time of the first Griffith’s Valuation. He held that property until in 1900 the property was renamed to his granddaughter, Mary McNeilly. The property was next door to John McDowell. The Will of John Wisnom late of NE DIVISION, Carrickfergus Farmer who died 5 November 1890 at same place was proved at Belfast by John M'Dowell (Junior) - son-in-law, of Loughmorne Carrickfergus Farmer the surviving Executor. Estate equally divided between daughters Nancy and Mary Ann. Nancy Wisnom and John McDowell were named Executors in original will signed on Nov 15, 1887.At the time of John's death, Nancy had passed. Unable to determine who John McDowell was married to at the time of John’s death.
Also in the NE Division during the Griffith Valuation are: Isaac Wisnom (Wisnam) (#90). b. 1810 in Duffs Hill; William Wisnom (b. 1791) leased land in the NE Division (#86) from 1862 to 1879 (In 1879, son Joseph Wisnom (b. 1829) took over the lease); John Wisnom (b 1816) leased land in the NE Division (#140) from 1862 to 1900 (. In 1900, son Frank W. Wisnom (b 1852) took over the lease on the 15 acres and managed it through 1920.); and Sarah Wisnom (?) leased land in the NE Division (#59) from 1862 to 1872. I am not sure where your ancestors property was located at this time, however, John Wisnom's #140 property is the closest to Lyndon's Park.
