No matter what, it pretty neat that your family has kept the tradition alive for 5 generations. In my family, the first son has had the same initials every generation on my dads side going all the way back to when the lived in Wales in the 1700's. my grandmother was a genealogy buff and traced it all the way back. Some of the names changed over the years... But the initials have always been the same for that first son. I wasn't about to break the string.
