I don't have much information, but I do have an at least partial list of their children. I have John Magrum, the son of Gregory Magrum and Magdalena Ottoni, was born December 1854 in Sandusky Co., Ohio, and died 1936 in Oak Harbor, Ottawa Co., Ohio.He was buried in Union Cemetery, Oak Harbor, Ohio. He married Elizabeth M. Madisen April 01, 1880 in Sandusky Co., Ohio.She was born November 1864 in Hjorring, Denmark, and died 1943 in Ohio. She was buried in Oak Harbor, Ohio. Their children were: Anthony J., Gregory,Henry Edward, Berta, George, Charles, Peter J., Robert, and one other for whom I haven't yet found a name. I hope this helps a little.
