I am looking for information on my grandmother's side of the family. She was a Luetzow (Lutzow)

Her father was Charles Luetzow, born in 1855 and emigrated to the USA in or about 1870. He settled in Wauwatosa (Milwaukee County ) Wisconsin. His wife's name was Magdelena Reinganz.

I am especially interested in finding his birthplace, and then the name of his church where he was baptized, etc.

Any help would be appreciated.
