I wonder if he knew that his cousin's mother-in-law, father-in-law and, eventually, husband, brother(s)-in-law and assorted spouses were buried there. I don't mean nth cousin however many times removed. I mean his dad's older brother's daughter's kin-by-marriage.
I wonder if he knew.
Because I _know_ he didn't tell us.
ETA: It occurs to me that if Harry's stone says "beloved husband and father", there _is_ a kid around somewhere. I just have to find them.
