The census of 1851 shows the family in Peterborough, Northamptonshire, at No. 3 Market Place. The Head of the house is not at home. Wife is "Ann COGHLAN, 31, born Jersey, Channel Islands." (Info from Wikipedia indicates her name was Amie Marie COGHLAN, nee KUHLY.)
Children are Charles, 8, born Paris, France; Frank, 2, born Wandsworth, Surrey; and Rosamond, 1 month, born Peterborough.
Also in the house is Mrs. COGHLAN's widowed mother, "Anna N. KIRBY" (KUHLY??) 69, born Earsham, Norfolk.
The 1861 census finds the family in Kingston-upon-Hull, Yorkshire. Head is Francis Coghlan, 55, "Author, Topographical", born Dublin, Ireland. Wife's name is spelled Amie. Son Charles, 18, is a "Comedian". Frank, 12, is an Apprentice Ship Broker. Rosamond, 10, is in school.
Wikipedia has quite a long article about the actor son Charles Francis COGHLAN and his family.
I am interested in the COGHLANs because Francis' daughter Frances married William Daniel MORRISON in 1850.
It appears that Frances Susan (b. 1824) and her sister Mary Catherine (b. 1822) were the daughters of Francis COGHLAN and an earlier wife named Catherine COGHLAN. In 1851, this earlier wife was still alive, and describing herself as "married", occupation "Traveller's Guide's Wife"....
