Fontains married in Floyd County, IN abt 1828-1831

I am looking for information on these Fontain(e) marriages in Indiana across the Ohio River from Louisville, Kentucky:

Name:Eliza Brindley
Spouse:Cincinnatus F. Fontaine
Marriage:15 Dec 1828 - Floyd

Name:Henry Schoolcraft
Spouse:Matilda Fontain
Marriage:10 Mar 1829 - Floyd

Name:Susan Burrows
Spouse:Jullius W. Fontaine
Marriage:22 Sep 1832 - Floyd

Are these Fontaines related? Anyone recognize them or know who their parents are?I am particularly interested in Matilda as I am fairly certain she and Henry Schoolcraft move to Louisiana 1840-1860 and their children James, Jane, Luke and Alfreda are all actors and artists.

Thanks in advance!
