I am looking for information on Owen Eugene or Eugene Owen Mohan (sometimes spelled Mohn or Moen), born abt. 1852, who may have been from Co. Monaghan. He married a woman from Co. Monaghan whose name was Catherine Shevlin or Sheborne (born abt. 1851). They were married in San Francisco, CA in 1873 and then moved to Sacramento, CA. Please let me know if there is any connection.
