For O'Lanes from Donegal/Derry you might want to look at O'Luinigh former lords of Cenel Moen (Gillacrist O'LUINIGH, Lord of Cinel Moen,' AD 1090), who originate in the barony of Raphoe, Co. Donegal. The O'Luinigh are said to have been push across the the River Foyle into the barony of Strabane and I beleive are the source of the O'Lane regiment in the War of the Three Kingdoms (below). For I believe Turlough Mac Art Oge (below) O'Neill's is the grandson of Turlogh Luineach, said to be named for his hosterage amongst the O'Luinigh where he later built his castle. http://freepages.genealogy.rootsweb.ancestry.com/~mhuintirluinigh/ "guarded with some five troops of horse of Colonel Philip Mac Toul's [O'Neill] regiment, Turlough Mac Art Oge's [O'Neill] regiment, and general-major O'Lane's regiment " http://books.google.com/books?id=4hFZAAAAYAAJ&pg=PA232&lpg=PA232&dq=%22o'lane's+regiment&source=bl&ots=DPR3yRMX7U&sig=o1AyH0TnIWrXqCZctGZ20vdgQ_Q&hl=en#v=onepage&q=%22o'lane's%20regiment&f=false
