Welcome to Ohio. My name is Jan Cortez. This State and all of its counties are up for adoption. If if you are interested in adopting the State or any of the available counties, please contact me. If your interest is more along the lines of providing materials, doing look-ups, typing, etc., I'd also like to hear from you.
For more details and information see our Midwest North District page
Even if you do not have a project we are looking for books, biographries, census transcriptions, cemetery readings, wills, bible records, etc, in text format so that we can index them for searching.
