Victor,
Welcome to WikiTree and the Bahamas Project! I looked, and there are already profiles for your grandparents, Thomas Victor Lowe and Marguerite Cates, so it will be easy for your to connect to the main tree. You just need to create a profile for your father, and then connect him to his parents. BTW, I am also a descendant of of Capt. Gideon Lowe ;-)
