I must remember that when I meet blank bewilderment from others who are quite able to count. The only reason for charts, like them or not, recommend them or not, is in the hope (often vain) that something of a quasi graphical/textual format will aide understanding which is why they are used in the schoolroom; and dare I say it, the boardroom! (think of Whiteboards, Spreadsheets & Power Point Presentations).Maybe, but I don't recommend using charts to calculate relationships - in fact I advise against it. The only chart you need to calculate relationships is your family tree, and the only skill required is the ability to count.
The only way I got my last Boss (he owned the Company and a shrewd businessman) to understand even a basic principle of whatever I wanted to explain was by producing a pie chart. He could relate to that instantly.
KISS -(keep it simple stupid) is a good start off point. I find that people can relate to straight forward direct line ancestors - Parent-Grandparent-Great grandparent - but the moment the family line branches off (excluding perhaps first generation Uncles & Aunts and with a bit of luck their spouses and resultant cousins), everything becomes blurred. Someone falling outside these parameters becomes ...a 'great/grand something or other' or a 'distant cousin of sorts'.
You mentioned quite recently how some people find LC complicated (hence seeking Forum members others to help), so it should come as no surprise that family tree relationships are equally bewildering to a good many people. The chart Norman produced is a big improvement on the well known Cousin Relationship Chart that can be found in Wikipedia (Google 'Cousin') and a useful aide in explaining relationship principles. Especially when combined with a Pedigree Chart. At least then you can explain generational counting principles.
