* half relations

[Johnwrosser]

I don't understand how FH calculates who is a half cousin?
My 4 x gt grandfather married twice and from his 1st marriage, he had 3 children, 1 of whom survived and became according to FH my 3 x HALF gt aunt? It follows that having calculated that then all her descendants are shown as HALF cousins.
From his 2nd marriage he had 8 children and these are shown as 3x gt gt uncles and aunts!

Which line are you descended from? The first marriage or the second? From what you've explained it would seem one of the children from his second marriage is your 3x great grandmother or grandfather. Which would make the other children 3x great uncles & aunts, and any relatives from his first marriage HALF relatives (since you are only related via your 4x gt grandfather). Does that make sense?

[Gowermick]

You are half related to someone if you only share one parent/grandparent etc. but not both!
e.g. If you father married again and had a son, the son would be your half-brother, because although you share a father, you have different mothers!

[Johnwrosser]

You seem to have got the reasoning behind it but it does look odd on the tree!

Some when considering relationships (particularly half-relationships) forget that the key individual is the most recent common ancestor.

If the most recent common ancestor happens to be two people (xGt Grandparents) the relationship is a "full one".
If the most recent common ancestor happens to be only one half of a couple (a single shared xGt Grandparent) the relationship is a "half one"

The fact that you can go back another generation to the parents of a single common ancestor is a red herring because they are not the most recent common ancestor.
