Interesting question! I'm not sure I believe in reincarnation for everyone, but I am open to the idea. I believe our souls are definitely connected to our ancestry. Family that has gone on ahead of us and that lived before us, can act as guides and guardians as we walk this earth. If we have lived before and have returned it is to learn something or experience something that we missed last time but that is vital for the evolution and enlightenment of the soul. For some, following a blood line might be necessary while for others, not so much. Hope that helps!
