John McVeigh was born in County Down, Ireland, about 1813. As we have seen in the article, Christina O'Rourke, Killowen to Chicago, John was a widower living in Dunnaval Townland in 1901 with granddaughters Christina and Joanna O'Rourke and a grandson James Doyle. John had been on parcel 38A and 38B in Dunnaval from 1866 onward according to the Valuation Revision Books.
We arrive at Selina (McVeigh) Kelly by way of her niece Christina (O'Rourke) Flood ... Christina O'Rourke, Killowen to Chicago.
