I am researching the Lynn Mohan family and found several censuses today that looked like they listed the Bogues as coming to America about 1892-1894. The Dempseys are in the national census from 1900 on to 1940. Just FYI, I just posted, last week or so, the stone that bears Catherine Bogue's name to Find A Grave. 1874-1899, perhaps that's not her, maybe the years are off, but anyway it is on the Mohan stone with Annie Bogue Mohan. I don't know the Bogue family, I am a Mohan. Great grand daughter to Alice E Mohan Clark, Ireland about 1852...still searching.
