Lilias Campbell was born 1674 in Scotland to Robert Campbell (c1645-1712) and Catherine Napier (c1650-) and died 1 August 1709 Scotland of unspecified causes. She married James Dunlop, 3rd of Garnkirk (1655-1719) 1689 in Scotland.
"The lawyer laird of Garnkirk's son, styled the third laird. married Lillias Campbell, of the North Woodside Campbells, who was the mother of sixteen children, and died at the age of 34 years. Some local authorities have questioned the possibility of such marvelous fecundity, but the carefully prepared record by the husband of this lady, among the Dunlop Papers, show twin births occurring more than once, and completely removes any occasion for doubt that may have arisen on that subject.
James Dunlop was succeeded by his eldest son, James who sold the estate of Garnkirk to his nephew James, who died in 1769."
