Third cousins once removed. To work it out
1. Count the number of greats from each of you to the common ancestor.
2. Add one to the smaller (or equal) number of greats. That will give you the x-th cousin bit (Think about it: grandparents make you 1st cousins, great-grandparents make you 2nd cousins, great-great-grandparents make you 3rd cousins and so on).
3. The number of additional greats in the bigger number of greats gives you the number of times removed.

In your example, Jazzo, the shorter chain is great-great grandmother. 2 greats + 1 makes you 3rd cousins. The longer chain is great-great-great-grandmother. That adds one more great so you're once removed.
