Just on the offchance: I'm searching for the Irish origins of my Egan ancestors, who turned up in Westminster in the early years of the nineteenth century. My gg grandfather was George Egan (b. Westminster 1837), the youngest son of James & Mary Egan. James was a builder, possibly the son of a Frederick Egan (if Irish naming patterns are anything to go by), but he must have died soon after George's birth, because Mary remarried - a Charles O'Donnell. Mary put 'Ireland' as her birthplace on the 1841 and 1861 censuses, and 'Ireland' is put as her origin in the St James Westminster Workhouse records. (whereas her sons are charged to the parish because their father, James Egan, had paid rates and taxes there). But on the 1861 census, there are two possible Mary O'Donnells in Westminster, both of whom put their birthplace down as 'Mayo'. Does any of this ring possible bells with your Egan research?
