Regarding Pattons and Donaghadee, probably related to the Pattons of Ballyvester. James Craig, grandfather of the 1st Lord Craigavon, worked for James Patton, who married Agnes Veacock. James Craig improved his station by marrying her sister, Alice Veacock some time 1810s. Would need to check the book again, Craigavon: Ulsterman by St. John Ervine.
One James Patton was witness in 1858 at the wedding (
civil record) of their son, James Craig (millionaire Whisky distiller, father of the future Lord Craigavon) to Eleanor Gilmore Brown.
New Zealand connection too - the daughter of the elder James Craig and Alice Veacock, daughter Alice Craig married Samuel Fergie (1864,
record) and the couple emigrated to New Zealand. Alice died in NZ in 1905 (
grave). Samuel Fergie returned to Donaghadee in his last years , dying with Lizzie Patton present (
record).
Alice's sister Eliza Jane married Hutchinson Waugh - their youngest child born 1873 (
record) was named Alexander Patton Waugh.
I hope this is of interest or useful to those looking up the Patton family around Donaghadee and links to the Craigs.
