| Cousins
A
/ \
B C
/ \
D E
/ \
F G
A is the parent family and has children B & C
B has a child D
C has a child E
D and E are cousins (or first cousins ... same thing)
D has a child F
E has a child G
F and G are second cousins
F is E's first cousin once removed
G is D's first cousin once removed
The 'removal' is the number of generations difference between the
cousin relationship.
Or mathematically ...
two cousins C1 and C2
1. Find the nearest common ancestor of C1 and C2, call it A.
2. Count the number of generations between A and each of C1 and C2,
call that G1 and G2.
3. C1 and C2 are (MIN(G1,G2) - 1)th cousins (ABS(G1-G2)) times
removed.
Of course, if G1 = G2 then there is no "removal" and if G1 = G2 = 1
then they are siblings.

| If someone is my first cousin, once-removed (e.g. my cousin's kid), then
I must be his first cousin, once-added, right?

Nope ... there is no indication in the term as to which direction you
are removed. The term removed just implies difference. You are his first
cousin, once removed, he is your cousin once removed. C'est la meme chose!

| Everyone else here seems to be using ULTRIX OS.
If you use VMS OS, you can be a first cousin, once deleted.

| Well, twice deleted is more than a bit difficult.

| True, Norman. Delightfully subtle, but true.
Does this explain why the only sort of relative illustrated in the
left-hand side of the .1 family tree is likely to be merely a MAN?
And does it explain that the more sinister of the two families
descended from the /root ancestor "A" appears to be U*IXians, and the
other (the dexterous side) seems to be a \gaggle\ of DOS-heads??

| I have a cousin I'd like to remove.
