The Mack, Schneider, and other Brethren marriages that have been discussed in the past week or so can be found in the Marriage Proclamation Records of the Court of Achtkarspelen, the latter being the region in Friesland where the Mack Brethren lived prior to emigrating to Pennsylvania in 1729. The (mis)spelling Suederen in Willoughby's book is "Sneeder," the "en" being a suffix. Seems that a Dutch "n" looks like an English "u." She married John Mack, son of Alexander Mack Sr. "Sneeder" is also the name given to Christian Schneider who married Susanna Mackingh, "ingh" also being a Dutch suffix. Susanna Mack is said in a note to be the daughter of Alexander Mack. The Dutch "Sneeder" is the same as Schneider in this country. Looks like two Schneider siblings married two Mack siblings. I have found seven Brethren marriages in these records of emigrants who were on the Allen. I suspect that the marriages in the Willoughby book were from these same Dutch records. Dwayne Wrightsman
