I was thinking about the initials in our family. Years ago when there were just the 5 of us, we signed Christmas cards and other correspondance KSTJL, indicating the first letter for each of us in this little family. Well in thinking about posting a comment I noticed that so far, we STILL have a different initial for everyone in the family. T married D and they had grandgirlee#1 N. Then J married his C and GG#2 H came along. So far no duplicates.
Ah, but when we get into extended family it gets crazy, K & an R, and M & H then a B and oops it all goes off my theory with another R and my sissy T and her C and more then more repeats and oh well. It works only for the immediate clan.
