Hi Julia,

That brings up an interesting conundrum. I differ from my real, biological,
cousin by 2 at DYS 388 but the Johnston who matches me 22/25 only matches him
21/25 and one of those differences is by a value of 2. If I use 22 as a
cutoff point I'm related to both but they are not related to each other.
Years ago I used a signature line, "Nobody said it was going to be easy."
