I don’t expect to get one definite answer here, but Google can’t give me one either. Some websites say they’re your second cousin, and others say they’re your first cousin once removed. I’m trying to figure out some family tree stuff so I need to know the difference between the (groups of) terms.
Yeah this was always confusing to me because my Dads cousins were closer in age to me, so “second cousin” always seemed to make sense.
