Hi Geof, It was common for Scottish families to name.... 1st son after father's father 2nd son after mother's father + use of mother's maiden surname 3rd son after father 1st dau after mother's mother + use of mother's maiden surname not her married surname 2nd dau after father's mother + use of mother's maiden surname not her married surname 3rd dau after mother + her maiden surname For 4 + males or females these could be named for parents siblings. Not all children were given a maiden surname as a middle name, some gave the Minister's or employer's name as a middle surname too. Hope this helps, Jenny - with plenty of paternal Scottish families and mother's paternal families of SSX
