Thanks so much for great tips, Beth. Will explore RAOGK and Winona GenWeb. And what is Dalby database? The links to historical info about Winona are fantastic. My ancestors were apparently there by 1857.
And the Edward Bembo we found in Racine, Wisconsin IS my Edward...I ordered Ed. and Catherine's marriage certificate from Minnesota Official Marriage System, and it say he is of Racine.
I, too, went on a roots trip; in 2002, I journed to Lac Qui Parle Co., in western part of the state, to get a feel for where my grandmother's family had lived. I live in Washington, D.C. suburbs, so this was really different and new for me.
Will work on lookups and possible requests from Minnesota Historical Society. Thanks so much again.
