I worked out the find a grave site finally lol.

I am so, so, so, confused with what the deal maybe with my grandfather.

I see what you mean by his fathers marriage record as William Henry Smith but then signed Felix Smith.

And I see the memorial record to Felix Smith, married to Mattie and the son Claude, along with a step son called William Richard Smith, which I think must be my grandfather, but then who is his real father, I have no idea.

Any other members who appear to share the same family line, do not show my grandfather, but strangely, the same is true for his first wife Loretta Thiel, she seems to not exist on other peoples tree's.

it really is a conundrum and I have no idea where to start lol :-(
