My Grant's appear to go back to Angus Grant in Abernethy in 1742 but I only have proofs for the line back to William Grant born in 1831 in Abernethy. He died 22 Nov 1903 and is buried at Newhills Aberdeenshire. William had 2 wives 1 Margaret Minto from Kincardineshire and Isabella Keith fom Aberdeenshire.
