Caughey family

Hello,

I am a descendent of James F. Caughey, born in County Down, Ireland in 1817 or maybe 1812.  There is also a James L. Caughey that may be an uncle.  Also John Caughey, born about 1801, may be the father.  I am not certain how all these men are related.  They emigrated to United States before 1836, as both James and John were naturalized in April 1836 in Rutland, Vermont USA.   I do not believe they were married at the time they emigrated, but John may have had a wife in Ireland that had died.  Any information about these ancesters will be appreciated.

Thank you,  Bellady
