There is some debate amongst my family currently on how to name my soon-to-be born son:
For ease of typing, I'm going to use first names only.
My grandpa is named Joe. He has a 2 sons one born in 1960 Joe JR, and one in 1962 John.
I was born in 1991 to John and named after my grandpa. I am Joe II.
My uncle had a son in 2000 and continued his name. He is Joe III.
Now I, Joe II, am having a son in 2022 and plan to also continue the name. What will my son's suffix be? III or IV?
My take: My uncle Joe JR and his son Joe III are in their own line of the family tree. When my father named me after my grandpa he started a different line and my son will be the III in that line.
What are the thoughts on this? I've struggled to find a similar example as in my family online.
