Found this website: http://infowanted.bc.edu/ , while cruising the internet last night. I haven't seen it posted on Ancestry.com in my travels through the message boards.

From October 1831 through October 1921, the Boston Pilot newspaper printed a “Missing Friends” column with advertisements from people looking for “lost” friends and relatives who had emigrated from Ireland to the United States. This extraordinary collection of 31,711 records is available here as a searchable online database, which contains a text record for each ad that appeared in the Pilot.

I've seen this information in a genealogy book at the Susquehanna County Library, Montrose, PA. This site makes the data available instantaneously..

Looked up 'Quinlivan' and it came up with these three people.

john Quinlivan limerick 1853 , Maurice Quinlivan (brother) is looking for him
maurice Quinlivan limerick new york city 1849 , John Quinlivan (brother) is looking for him
michael Quinlivan clare 1859 , Ann Quinlivan (sister) is looking for him.

There are more details besides above for these individuals.


Enjoy
