I don't think you will find a copy of "The Trueblood Family in America" anywhere. It has long been out of print and those who have one will never give it up.I have a copy. If there is any information you need I will be glad to look it up. I looked at the line you gave, Amos-Joshua-Thomas-Benoni( m. Bridget Ann Gregory)-Elizabeth. This book statesthat Elizabeth, the dt. of Benoni and Bridget,was b. 1813 Camden County, NC and d. 1815 in Camden County. Is this an error or did you skip a Benoni? Benoni and Bridget had a son, Benoni Gregory Trueblood who had a dt. Sarah Elizabeth who married Milton H. Piety in 1870. They had children Ozry, Agnes,and Ernest Ray Piety. Is this correct? If I can be of any assistance, please let me know.
