Hi Robert, Welcome to WikiTree! Yes, on WikiTree you will be able to see information about the DNA tests taken by others you're related to. However, this will only work if you've entered your ancestors in WikiTree. I encourage you to sign the WikiTree Honor Code, and start by adding your parents to WikiTree. Then add your grandparents, etc. Be sure to enter dates and locations for births, marriages and deaths in the data fields. In the Biography area, always enter your source for the information you're entering for a profile. And always check first to make sure the person you're entering doesn't already have a profile here on WikiTree. If you have any other questions G2G is a great place to ask them!
