Cathy, the four brothers story was a RUARK item, not Driskell. John Ruark md. Mary Driskell, granddaughter of Denis Driskaol. Here is what I show on him: From A Somerset Sampler by Pauline Batchelder:
Many of the family were saddlers. William Driskill patented tract Kingsale in 1694. Dennis Driskell (d. 1721), possibly a son or brother of William Driskell, is believed to have been a mariner; owned tracts Cork and Kingsail, among others, at the time of death; earlier he had owned a small island, South Foreland, on north side of mouth of Manokin R., which he sold to Graves and Richard Jarrett. " The will of Denis Driskaol, as it was spelled, was drawn July 1721, not long before his death. He leaves his wife 350 acres during her natural life, or only 1/3 if she marries, then the 350 to son Richard. Sons Denis and James also receive tracts of land, one called Cork, possibly a hint to their homeland. Another tract was called Kinsale, a town in Co. Cork, Ireland. Son Moses appears to have received a boat and furniture lying at the seaside. Daughter Hannah Holson(?) received a cow and calves. The will is witnessed by Peter and Dorothy Wilson, a John Roach (?) and Margaret Conner. In addition to the children mentioned in his will, Denis also had another son William in 1691 who may have predeceased him.

I believe they were Irish, not English. Gene Rooks, Gotha, Fla.
