ysth are my initials (actually yst, but cpan won't let you use just three letters so I added another and then used the same four here). My full name is Yitzchak Scott-Thoennes; the Thoennes was mine from birth, and the Scott from my wife. Hyphenating was a last resort after we failed to pick a completely new name to share; she just wouldn't go for "Baggins". Amusingly, just a few generations back, my paternal ancestor was named Brown but adopted into a Thoennes family, while my wife's paternal ancestors were named Shwartz or some such but changed to sound more English after immigrating to England. I often get entered in brain-dead hyphenless software programs as SCOTTTHOENNES and the clerk finds the three T's in a row hard to believe.
