I am also looking for a Henry Becker, married Catherine Mode, St. Clair County 7/20/1854.
The Mode's are the one's I am mainly interested in. The Catherine I'm researching was married to Valentine Sr. Both were from Germany or Bavaria. They had:
Mary or Anna (probably Mary Anna).
They lived in Okawville, Washington Co., IL
Is this a connection? Please email me at firstname.lastname@example.org
