We had a family tradition—I think this used to be common—of naming a son after the maternal grandfather...first name=first name, last name=middle name.
Grandpa=Robert David Smith
Baby=Robert Smith Jones
Ours went for, at least four generations; but my daughter had no sons.
I like family names. I think they inspire a sense of history, tradition and belonging.
My father died 2 years before my son was born. He would have loved my son and been proud that we named him after him. I knew the name came from my father’s mother’s family but did not know how long it had been in use until I did some genealogical research into her family. It goes back many generations all the way to the 1800’s in one combination, form or another.
