Subject: Scottish Naming Customs
"The general custom, to which there were some variations, was to name children as follows:-

The eldest son after the paternal grandfather
The second son after the maternal grandfather
The third son after the father
The eldest daughter after the maternal grandmother
The second daughter after the paternal grandmother
The third daughter after the mother

Younger children would be named after earlier forebears, but the pattern in their case was less settled."

("In search of Scottish Ancestry" by Gerald Hamilton-Edwards, Phillimore, 1983 Edition).

The book goes on to discuss the most common variations, at greater length than I can summarise here.
