Christian Gutknecht was born in Bischweiler Germany on 25 Jun 1722. He was baptized at the Reformed Church in Bischweiler on 28 June 1722. His date of birth was calculated from the records of the Germantown Reformed Church records, which state he was buried on 27 December 1795, having died the previous day, at the age of 73 years, 6 months and 2 days. The church records of Bischweiler and the Bischweiler Stammtafeln yield the following information. Johann Gutknecht, carpenter, was born 18 January 1691 and died 18 July 1762. He married first, Anna Barbara Kieffer, born 25 Mar 1688 and was buried on 4 Mar 1726 at Bischweiler, age 38 years.

After the death of his first wife, Johann married second, 10 Feb 1727, to Mary Magdalena Grob, born ca 1695, buried 20 Sep 1741 at Bischweiler.

There is further information on the Grunholtz line in the Church Records and the Bischweiler Stammtafeln.
I believe the evidence indicates that Christian Gutknecht of Germantown and Christian Gutknecht of Bischweiler Germany are one and the same. From the church records that I examined, there was no evidence to indicate that Johan Michael Gutknecht and Johan Georg Gutknecht, more commonly known as Michael and George Goodnight, were siblings of Christian Gutknecht of Germantown. Perhaps a link can be found further back to indicate they are related, but not as siblings. I believe the Gutknechts originated in Switzerland and migrated into Germany during the many wars in that area.
