After marrying in 1896, the Abercrombies had four children: Elizabeth, Lucy, David and Abbott. Elda Castle is named for the first letter of each of their four children. The castle ended up becoming a retreat and place of comfort for the Abercrombies after two of their kids died in tragic accidents.
