Ken, you are correct about the generations.
I'm confused as to where to place the double or perhaps triple parentheses for
multiple generations.
In writing, brackets and braces as well as parentheses are used, but the AHS rules indicate
only the use of parentheses if I understand the rules correctly.
Since you recognized the multiple generation chain clearly, perhaps the above is
okay.
Sorry, I wasn't very clear with the initial question.
