Marriage certificate look up for..

Paul Thomas Smith marrying Helen Grigsby.I've read they had gotten married twice.I know they had a son January of 1936.I'd love to locate both marriage certificates in order to keep up with tracing back their footsteps..

I've also read that Helen had married someone with the last name of Angle.Would love to find that one as well.
I have no clue if that was in between marriages with Paul or if she had married Paul twice and then married Mr. Angle.

UGH!:):):)Would appreciate any and all information you can find.From what I understand both Paul and Helen were both brought up in Cass County.

Sincerely,
Sunshine
