Hi, my link to the Keanes is pre-1800 when one of the girls married a Cluxton somewhere. Her daughter subsequently married John Spotswood.
The Keanes/Kane’s were in Cork from quite early.
There are records of a couple of early colonials in America but might be too early for you?
Kean (or Kane), Thomas
In his letter to Robert Simms of 18 October 1802, John Caldwell jun., writing from New York, included Thomas Kean in his list of ‘Belfast People here’.84 He is said to have been the brother of William Kean (q.v.), but was possibly confused with him.
Kean (or Kane), William
A former employee of the Northern Star, Kane was reported to be Henry Munro’s aide at the Battle of Ballynahinch. He was captured and imprisoned, but escaped and made his way to America. He settled in Philadelphia where he was visited by Samuel Neilson (q.v.) in 1803 who was seeking advice about setting up an evening newspaper.
Thomas McKean, a prominent member of the Friendly Sons, served as first president of the Hibernian Society. He resigned when elected governor of Pennsylvania, a major Democratic-Republican victory. Opponents had accused the son of Ulster immigrant parents of seeking ‘to import “Twenty Thousand United Irishmen” into the country as men who understood “true liberty and the Rights of Man”.’ Foes also accused McKean of having opposed war with France but willing to fight Britain.1 The first president, with roots in colonial-era migration, thus identified with the outlook of post-revolutionary migration.2

Thomas McKean had once been a respectable Federalist, but his sympathies for the French Revolution and antipathy towards the treaty reached with Great Britain led this son of Irish immigrants inexorably into the Republican camp – a shift which in 1799 gained him nomination as the Republican candidate for governor of Pennsylvania (ibid., p. 225
