DALRYMPLE
As described in historical dictionaries
An Etymological Dictionary of Family and Christian Names (1857)
(origin: Local) Taken from the lands and barony of Dalrymple, in Ayrshire, Scotland. The name is said to be a corruption of the Gaelic Dale-roi-milleadh, which signifies "the valley of the slaughter of kings," and the place was so called from a battle fought there before the Christian era, in which two kings, Fergus and Coilus, were slain. According to others, it signifies "the valley of the crooked pool." I think the name signifies "the valley on the margin of the pool," from the Welsh Dol, a valley; rhim, the edge or border, and pwll, a pool. It is very nearly the same in Gaelic; Dail, a vale, troimh, by, along the whole extent, and poll, a small lake.
