According to an early Calhoun County history printed in the "Calhoun Farmers Advocate" [10 Apr 1891], Roma Maranville came to Calhoun County 1855-1858. I've found him and his family in Jackson Township [Lake City area] on 1870-1880 censuses.
Roma, his wife Emeline and two younger children were living in Lincoln Township, Page Co., IA, in 1900, but all are listed on a Calhoun County Death Index [found on the Calhoun County GenWeb web site ].
Roma's wife was Emiline Bunting. Their son James Isaac m. Alda Belle Runyan; Alvin m. Mary Alice Robey; daughter Eliza supposedly married a Harrison and Ella m. Benjamin Garfield Mahon. Alvin, his wife and three children are buried in Lake Creek Cemetery.
I'm not aware of the Maranvilles having a connection to any of the surnames you mention but have not followed Roma's family for more than 2-3 generations. I've never seen a picture of Roma; he's not one of my direct ancestors. I've been working on all members of the Ashtabula Co., OH, DeMaranville clan, especially those who "went missing."
The folks back in Ohio seem to have completely lost track of him. In a family reunion article in the "Conneaut Reporter" [18 Sep 1889], the author [one of his cousins] wrote: "John Maranville married Sally Brown and went to Michigan, and there lost his wife and most of his children. They were thought to be poisoned. Two boys were left, Ferris and Roma. I do not know if they are living."
That was a bit of a challenge but managed to track Roma to Iowa and his brother, Ferris, to Fulton Co., IL.
