Below is a link to a list of Manson's family members. It should be noted however that many of the young people that may have had contact with Manson and his regular group would just drift in and out due to the transient ways of the people of that era.
There were around 30 young children that lived within the 'family'. Not all of them were born into the 'family'. Some came with their mothers, Manson's followers, and some were born into the family, though I doubt that the mothers ever knew who the fathers were. It was Manson Family policy that everyone had sex with everyone else, and frequently, so I doubt they were much concerned with paternity. As to how many were actually Charles Manson's may never be known. Those children are now middle-aged, some may not even know of their strange time in the family. It may be a good thing if they don't remember.
