While checking out errors, I encountered what I believe to be a glitch.
The 305 error said "Father too old", but the error was in the child's birth, in that it was one century too late. All other births were in the correct century, but both the 305 and 306 "Mother too old" were tripped.
Perhaps this is nit-picking, but another error code might more clearly explain the error.
I've corrected the child's birth date.
