My father's name is Micheal Ivan Anders and his mother is Wanda Lee Salter. I need help finding her Spouse and/or my Gpa.

Does anyone know of any tricks of the trade to track this info down? I've tried all I know of.

I'm also having issues finding anyone on the Salter side. I think Wanda's fathers name is Ivan Salter and was married to a Mary A Watson.

Thanks for any leads!
