I live in Cuyahoga County, Ohio. I am the only member of my family who lives in the county, and I have had only a few relatives who have lived hereabouts over the years. Still, I do Cuyahoga County research for clients and friends and I am impressed with the number of resources that are available, many provided online complete with indexes and often with linked digital images.
The advent and development of the Internet has brought many guides to these Cuyahoga County research resources. Perhaps the best known is Cyndi’s List, created and maintained by Cyndi Ingle. She provides 144 links in the section of her website that provides guidance for researching in Cuyahoga County. Go to http://cyndislist.com/us/oh/counties/cuyahoga
Another valuable resource is found on the FamilySearch.org wiki pages specifically for genealogical research in Cuyahoga County. This is a work in progress with contributions by volunteers. Go to Cuyahoga County, Ohio Genealogy.
