Mayrose Ancestors in Oldenburg

Just joined this list and hoping that some list members might be able to point me in the right direction. My 2nd great grandfather - Henry Mayrose - was born about 1850 in Oldenburg. I believe that he came to the United States around 1868 and he married his first wife in 1869 in New York City. After his wife died, he married again in 1899. He lived in New York City until his death in 1908. His 1899 marriage certificate shows his place of birth as Oldenburg and his parents' names as Christopher Mayrose and Marianne Lehonkuhl.

There is a group of Mayrose families in/around the State of Iowa (USA) whose ancestors hail from Oldenburg. Their family tree shows a Christopher Mayrose being born in Oldenburg around 1807 and marrying a Maria Catherine Schockemohle/Stockmuller. The tree shows three children of this couple - Caroline (born about 1853), Herman Joseph (born about 1854), and Barney (born about 1861).

I am trying to determine if my Henry Mayrose is connected to the Mayrose people who settled in Iowa (the older sibling of Caroline, Herman and Barney???). All I have at this point is the common birthplace of Oldenburg and Christopher Mayrose being the father of Henry and the other three children.

Wondering if there are church records, or other information, in Oldenburg that might help me determine if there is a connection. Appreciate any help!
