Frederic ( no k) Dudgeon and Mary Clark came from Ireland. They lived then in Brooklyn, NY. Even though the date of birth of their first child, Frederic C. Dudgeon is listed as March 12, 1855, is probably correct, it conflicts with the 1854 and 1858 arrival dates. There may have been a sister, but I cannot find her. I believe ( know) that Frederic Dudgeon died early in their marriage. Mary then married Samuel Bromagen and went Illinois where Frederic C. attended college. From there the Bromagens moved to Kansas. Frederic C. died 1898 He was the father of my grandfather, Byron Dudgeon. Mary died Clay County, Nebraska, June, 1903. I think they had a daughter, Rachel. Samuel died about 10 years later, and buried veterans cemetery, Ft. Leavenworth, Kansas. I have found no immigration, naturalization, marriage,death or obituaries for Frederic or Mary. If this leads you to our (your) original question, please contact. I do not know how this gets answered and transmitted through this site
