My mother’s sister married one brother
Their cousin married another brother
Pretty common in farm country of western NJ.......
“My mother’s sister married one brother
Their cousin married another brother”
The scenario you described would not likely be a problem, assuming the brothers were from a different family.
In Hunterdon County my mom’s aunt married a man with the same last name... he wasn’t directly related, however. I also dated a girl that was living near where my family had roots in Hunterdon... and found out we were like sixth cousins related by marriage.
