There is an amazing genealogy site online that looks for your ancestors all the way back to 1802.  They found someone for a friend of ours, who had wanted to complete a family tree for their mother, and her cousin.  All they had was the last name, and city, and this site found the person for them in a matter of about a minute or less.   Here is the link: http://www.searchyourgenealogy.com/index.asp?joinid=cxWjQvfJvW18d7pwbu88Yr3qTPKUOPw.  They can even find the family crest or coat of arms if that information applies, and they can search in other countries.  If you don’t want to join a web site, here is another option that looks very all-inclusive and might be able to track down James Lynch, for you: http://www.familysearch.org/.
