"The Evangelical and Reformed Historical Society," is located at 555 West James Street, Lancaster, PA. Ph. (717) 290-8711. They have been very helpful to me and to my knowledge don't have a set fee; I gave a $25.00 donation however I had a lot of research to request. I suggest you write them first with your question to receive their research procedure at the present. The Reformed Church is now the United Church of Christ. Margery Borger Sacramento, CA
