Harold Henderson has been a professional writer since 1979, a professional genealogist since 2009, and a board-certified genealogist since 2012. His research focuses on the Midwest and its feeder states. He has served on the board of the Association of Professional Genealogists and as a trustee of the Board for Certification of Genealogists. With Kimberly Powell, he developed and taught the five-day institute course "From Confusion to Conclusion" on writing proof arguments. He has lectured nationally and published more than 100 genealogy articles (midwestroots.net/misc1). Family histories for portions of the Bassett, Berry, Mozley, Scholes, Ackerson, Lowe, Flint, Thrall, and James families are in varying stages of completion and publication...but at any given time he would probably rather be reading a grantor index.
