They would be the fourth cousins. They share a common 5 Great Grandparent.
That person would be either me or my sister...if the cousin of me great uncle was my great grandfather. If the cousin was another of my great uncles, then the person would be my cousin. Example 1: My dad has a brother who is my uncle. That uncle has a father who is my great uncle. If his father or mother had sisters or brothers who had kids, these kids would be cousins to this great uncle. one of them could be my grandfather. so my grandfather's granddaughter would be me if I am a girl or my sister if I am a boy. Example 2: In any level of the family tree there can be cousins...children of my uncle or aunt. when they have kids they are second cousins...children of first cousins. If these second cousins have kids, they all are third cousins. So since my great uncle had a cousin which was 2 generations above me...the next generation would be second cousins and the third generation would be third cousins. If my grandfather was not the cousin in question, then the cousin would be someone else on the same generation level, 2 levels above me and the granddaughter would be on my level and therefore my third cousin.
