We had two equal traditions, both applying only to first boys.
In DH 's side the names go traditional Christian name 1+ Scottish surname before ordinary surname, next generation traditional Christian name2 + Scottish surname before ordinary surname, ie alternating down the generations, for nearly 200 years.
In mine, there's a first name, one of those surnames that became a first name, given to every first son, down the generations for longer than that.
We compromised. Poor baby had three names pre surname. Alternate Christian name, my father's name, Scottish surname, then our surname.
I liked the tradition on my side, liked my father, but didn't see why I should have what I wanted and DH not. So was happy for baby to have the my side one as a middle name as v unusual indeed, whereas the Christian names in DH's side are standard, classic names, so not lumbering infant unduly.
I'd have regretted breaking the tradition too.
