I found a Michael Kellett today in the 1890 Police Census of NYC, NY. He's shown with a Bridget Kellett. Age for both shown as 29.
The name is spelled Kellet (with one t) but I'm relatively sure he is the Michael I was looking for.
My great grandfather is Peter Kellett - born in Ireland in 1852, immigrated to US in 1880, naturalized 1885.
In 1888, Michael Kellett immigrated to the US on the SS Britannic. His age on the ship's manifest is shown as 24. He naturalized in 1893, his witness was his brother Peter, Michael's occupation was tailor. I had an address on the naturalization papers and several in NYC directories and looked for the most likely address for the 1890 Police Census - and found Michael. It doesn't seem as though this is your Michael Kellett - though it's odd he's also listed with a Bridget. Is this of any help?
A Patrick Kellett also came to the States in 1880, 2 weeks later than Peter, naturalized 3 months later than Peter, lived next door to Peter in 1885 (their naturalization year). I have to believe they're related (Patrick is about 2 years younger than Peter), but I can't document that.
I also can't find the county in Ireland that these three Kelletts are from. Does anyone out there know anything about them?
Peter was married to Ann McEvoy; his parents were Patrick Kellett and Mame(?) Caffrey. Ann's parents were Patrick and Mary McEvoy. She had a sister named Catharine (McEvoy) Garrigan, who was born in 1849 and came to the States around 1884.
Any help would be appreciated.
