You can try to see how these people fit in your tree, but you are really going about it backwards. You can only reasonably start at the present and work your way backwards in time with any degree of success. Not find a possible distant relative and hope to fit it in your tree. Do you have anything more than Herman Smous who was born in 1943? Where was he born? Do you have anything about his parents? Maybe we can locate the parents in a census and find some more clues. Good luck.
