Full Identical by Descent match with a 3rd Cousin

Normally, one expects to find either Half Identical by Descent (HIBD) or Full Identical by Descent (FIBD) matches with your genetic relatives. Generally only close relatives through double 1st cousins are expected to have FIBD matches. I have a FIBD with one of my multiple 3rd cousins. The Family Inheritance chart from 23andMe is below:
The FIBD segment is on Chromosome 19. I do not have an FIBD match at that location with my multiple 1st cousin who has a similar relationship to the 3rd cousin.

I am interested in learning of any other FIBD matches with cousins beyond the 1st cousin level.
