Sorry, there are many Henry system variations used for ancestral trees, particularly variations to avoid ambiguities when there are more than 9 siblings. For ancestral trees I have used for about 30 years what I consider a Henry system, using digits for males, letters for females. It is quite similar to that used by H. N. Kenyon in his 1935 book, "American Kenyons". Long before that topologists have used a Henry-style system to unambiguously label the branches of a tree. I regard the alternation of letters and digits as a cleaver variation on other forms of the original Henry ststen.

Please, let's end this thread now!

It is not a Henry system. So you can refresh yourself look
