Just wondrin’? 25% compares to a full sibling or parent/offspring pairing – what about this one?

This is a barely post-war time pedigree that I came across today. I understand the times were harsh . . . . but jeesh!

This is the closest pedigree I’ve found. The COI from AENA is done to ~ 8 gens. Anyone have one closer?

(Sorry about the fuzzines – paint didn’t like the bright colors).
