Narrowing my search for Cawley ancestor
I'm an American of Irish ancestry on all four sides. The earliest immigrant in my family was my great-grandfather, Patrick Cawley, who settled near Troy in upstate New York. His Alien's Declaration of Intent for U.S. citizenship in 1855 states that he is 30 years old, was born in Sligo and "migrated from the Port of Sligo and landed in the United States on the 30th of June in the year 1847." There is no family history of his having any siblings who followed him here. He may have been the last surviving member of his family during Black '47.
Are there birth records as early as 1825 in Sligo so I could determine possiblities for his home parish?
I have had no luck searching passenger lists on this side of the Atlantic for that date. Did ships from Sligo go to various destinations? I surmise that he could have arrived in New York City and gone up to Troy, or arrived in Canada and then down to New York State. Were coffin ships leaving Sligo during that terrible time registered, or kept under the official radar by unscrupulous landlords?
Any help would be greatly appreciated,
James B. Cosgrove
