The McIlwain (all spellings) Project seeks to find common heritage through sharing of information and DNA testing. Any variant spellings are welcome. If your Surname is missing and should be included, we'll be glad to add it. We want to actively promote the advantages and benefits of using DNA genealogy to complement traditional, records-based research. We invite you to participate in the MCILWAIN DNA PROJECT. To join, please proceed to our sign-up page or contact a project administrator.
