Hello Jen, I found this among my many "useful" printout lists for genealogy. I think it is the Scottish naming pattern: 1st Son after Paternal Grandfather. 2nd son after Maternal Grandfather. 3rd son after Father. 4th son after Father's brother. and so on until no brothers left, then moving on to the mother's brothers,etc. 1st daughter after Maternal Grandmother. 2nd daughter after Paternal Grandmother. 3rd daughter after Mother. 4th daughter after Mother's sister. and so on, until no sisters left, then moving on to Father's sisters,etc. Hope this helps. Cheers from Tasmania AEnone.
