After more research, I think my ancestor, Frederick Miller, was born and/or baptized in the Swamp Church in Cocalico, Lancaster, PA between 1786 and 1788. His probable parents, Maria Elisabetha (Achebach) and Friedrich Mueller aka. Frederick Miller, have another child:in Nov 18 1789 from Swamp Church record, Rev. John Christian Ammann. . 1787-1790: father: Frederick Miller (Mueller), mother: Maria Elisabeth, sponsers: Georg Achebach and his wife Anna Marie Trexler. There was a period of supplied pastors in the 1786 - 1787 period. I am hoping there may be some local records for that time. Thanks for your help!
