Just thought I'd add what I received from the "Historical Research Center" on Blankenship. The earliest references of the name is a record on Anna Blanckinship, who married Robert Robertson, in Saint Mary's St. Marylebone Road, London, on December 8, 1687. Abigall Blenkinship married William Thompson in Saint Mary's, Carlisle, Cumberland, May 25, 1692 and Alice Blenkinship, daughter of John Blenkinship, was christened in Bromfield, Cumberland, August 13, 1741 and Aaron Blenkinsop, son of John Blenkinsop and his wife Martha, was baptized in Ovingham, Northumberland, August 19, 1792.
