I am Richard L. Herrick, President of the Herrick Family Association (HFA). The HFA is currently preparing for the second printing of Volume I of the third edition of the Herrick Genealogical Register (HGR3) early this month. John Herrick and Nancy Platt are included based on having been in the Ephraim of Beverly chapter of 1885 edition of the HGR.
The HFA is interested in the descent that you have and if you wish to submit it we will include it in the Addenda chapter of Volume III of the HGR3 due to be published in 2010. Volume II will be ready to be published late this year or early in 2009.
