Hello Jean,
Henry Richmond, bap 24.2.1828, who married Mary Jane Henderson on 21.1.1859, was my gt grandfather. The parents of the siblings John, Jane, Sarah Ann, and Charles are listed in the Parish of Annagh as John and Sarah Richmond of Cornadarragh. Also listed in the records are 3 other children as having been born to John and Sarah Richmond although no addresses are stated. The tree may have looked like this: Geoffrey b.15.4.1816, William b.14.9.1818, (there may have been 1 or 2 children born between 1818 and 1826, a female who married Morton, and/or George Richmond), John bap 5.3.1826, Henry bap. 24.2.1828, Jane b.c. 1831, Sarah Ann b.c. 1833, and Charles bap. 24.5.1835. My grandmother, Elizabeth Jane Richmond b. 29.12.1872, and number 7 of 9 siblings by Henry Richmond and Mary Jane Henderson, married Robert Crozier. Cornadarragh townland can be confusing, as I was told, by a Richmond of the above family, that another family of Richmonds also lived at Cornadarragh although the 2 families were not related. Anyway, as the mother of Henry Richmond bap 24.2.1828 was Sarah and not Janet, it does seem that this Henry is not the son of John Richmond and Janet Henderson.
Regards, Kilroot
