Collateral blood relatives are relatives with indirect blood relationship, that is, relatives who are not lineal blood relatives but are of the same ancestry. My uncles, aunts, cousins and myself all come from grandparents. I am the first generation, my parents, uncles and aunts are the second generation, and my grandparents are the third generation. These relatives are all within three generations, so my uncles, aunts and cousins within three generations are collateral blood relatives.
