I am trying to determine if my Grand Mother was Manx. I believe she was born on the Isle of Man in 1860, but I don't know what her family name was. Her Christian name is Agnes and she emigrated to the US (New York) in 1869. Our family history suggests that her father may have been an American but her mother is listed in early NY census data as being "English" I believe possibly Manx.

So, does anyone know of a way to look up female babies (Christian name Agnes) born in 1860 on the Isle? Since Manx birth registration was not required by the government, I expect baptism records might be the best source of data.

Thanks for your help.
