Fuzzy Genealogy Lines

Laurence has taken an interest in his genealogy lately, and I do believe he has it all figured out. Here was our conversation this morning...

Laurence: How much Irish am I again?

Me: One-eighth. Your great-grandfather on dad's side was 100% Irish.

Laurence: How much French am I?

Me: Also one-eighth. Baka's dad's family was from France.

(Pause...calculating...)

Laurence: OH! Then I must be A LOT Maryland!
