Relationship question please

[Rachel]

Good day all on April 1st????

I have a new distant cousin and would love to know our relationship but my braincell seriously doesn't 'do' this sort of thing, even if I have a relationship chart in front of me!
(failed maths 'O' level).

Right ...

Cousin's Great Grand Aunt married an older brother of my Great Grandfather.

Does this mean we have Great Great Grandparents in common or is there a 'removed' or 'half' in there somewhere?

TIA
