I did some more researching on Scotlands People. The two most probably entries for Agnes Wardrop's parents were:- Alexander Wardrop and Bessy Peebles, married 1.12.1695, Linlithgow. Names Alexander and Elizabeth carry through. Or Issobel Thomsone maried to Alexander Wardrop at Livingston 31.12.1700 - although this is after the most likely birth date for Agnes (3.2.1697 - Livingston) I tried searches for siblings of Agnes with Parents Alexander and the only one I came up with was a Patrick Wardrop 1695 - a name not carried through. I found no Sophia or Helen. I tried Googling Kingscavil churchyard but no joy on finding gravestones. Any more thoughts??
