Kahlers from Minnesota

Looking to connect with anyone else who has a Kahler connection in Minnisota.I am looking for anyone with a connection to John Theodore Kahler and his wife Annie Elizabeth Reichel Kahler.They lived around Dundas, or Red Lake Falls in the late 1800's.They had four children:Marie, Walter, Edith and Alice.Marie was my g-grandma.I know that John T. was born in Canada, and Annie was born in New York.But my info ends there.I would sure like to find more about John or Annie.Thanks.
