Perhaps it was illiteracy or accents that resulted in the various spelling variations of this name. Very difficult to search the records when you give the surname GAGHEN and their childrens births were not registered with the surname
GEOGHAGEN. Fortunately I have the South Australian CD"s of births, death and marriages and can search using wildcards or simply the letter G and parents Thomas and Margaret.
There were
two Thomas and Margaret
GEOGHEGAN and alternative spellings, arriving in 1855 although the
FITZJAMES is officially shows as 1856 as it arrived 31 Dec 1855.
