Wisnom/Wisnam

I am seeking any records of Wisnom's in Larne in the 1700s or earlier. 

PRONI's records show a Captain John Wisnom living in Larne in 1760. There are records of Wisnoms/Wisnams in Carrickfergus and Ballycarry as early as 1791 regarding a lease of land at Duffs Hill, Carrickfergus to Wisnom & Co. Possible births of many in the Carrickfergus area as early as 1744. Capt. John Wisnom is the first link I have found to Wisnoms in Larne.

Any insight or information would be greatly appreciated. 

March 5, 1760 - Searched PRONI’s general on-line catalogue. Only reference of a Wisnom in that area was D2095/18:

“In the Belfast Newsletter, March 5, 1760 "the snow Captain Breton, mounting 10 guns and men answerable, commanded by Captain Robert Wilson" was advertised to sail from Larne for New York, the 1st April ensuing, wind and weather permitting, "any who inclined to indent as servants, go on redemption as passengers, or had goods to ship or freight, were to apply to W. George Dunlop of Ballycastle, Captain John Wisnom or W. Hugh Montgomery of Larne, or W. Thomas Gregg of Belfast." The voyage to America, which in those days would take perhaps 3 months must have entailed many hardships to the passengers in these over loaded sailing vessels."
