Nothing posted here for awhile, but I have an account that is somewhat different about how the Sedams got launched here.Heinrich Rycken Zuidam (which meant south dam)came in the 1600's ... I don't have handy access to the information and dates because I am travelling right now, but I found his baptismal record in Zutphen, Holland, which is near Appledorn, some years ago. Beutiful little town.He was born about 1630, as I recall. Came to America around 1660. I have something that says the name became Suidam, they Suydam, then Cornelius Suydam changed it to Sedam during or after the Revolutionary war. Still a bunch of Suydams in the Hudson River valley. He was the guy who ended up coming to Cincinatti in the 1790's (appx) and founded Sedamsville, still there to this day.He had 4 sons who spread out from there, because they kept getting flooded out.Hence the Sedams all over Southern Indiana.I have more detail if anyone is interested, but I am guessing someone has done a lot more work than me and may be willing to share it.
