Hatzfeld is located in Hessen just a few miles to the east of Elsoff, Kr. Siegen-Wittgenstein, Westfalen. There are some entries of Hatzfeld residents in the Elsoff church registers. Baptisms, marriages, and deaths/burials in the villages of Alertshausen and Beddelhausen were recorded in the church registers of Elsoff during this early period. And at this time Elsoff was a part of the Grafschaft of Sayn-Wittgenstein, but Westfalen as it is today. In addition to the church registers, there are two castle archives: one is at the castle at Berleburg, and the other is at the castle at Laasphe. I think that most of the Pfeil data extant would be at the castle at Laasphe. Access to the early civil records in both castles is difficult if not impossible because they are in private ownership, and, to the best of my knowledge, an archivist is not employed. Several local historians and other professional scholars do, from time to time, publish data from the archives in the excellent local history journal entitled "WITTGENSTEIN" which is published quarterly, and is available at Harvard U. and in the Family History Library, SLC among other places. Finally, Michael Pfeil's home web page contains a ton of Pfeil family research (in German, of course!), and can easily be accessed.
