In order to identify the Yoders with unknown names but known DNA, the father of Christian, b. ca. 1700, has been listed as Yoder YR. The Yoder who died at sea in 1742 leaving "widow Barbara" is YR1, and Christian is YR2.
You can Google the "Swiss Anabaptist DNA" and the "Yoder DNA" projects.
One rather confusing part is that Christian's haplogroup (clan) was listed as I2b1, but later it became I2a2a, and it also is called M223.
The good part is that the Joder line from Christian, b. 1571, and his son Jost, b. 1607, and also some named Bauer, Baumann, Kaufman, Lehman, Martin, Shirk, & Zimmerman are I (clade), considered by some to be the only "native European" group. I and its mutations make up about a fourth or fifth of the Europeans tested. The majority are R and its mutations.
Descendants of several Pennsylvania Yoders share mutation 16 at marker 19, which identifies them as sharing a common ancestor. Descendants of YR2 have been tested and share the 16 at 19 mutation. Strangely, some who think they are of this line do not have that mutation. Also, Caspar, b. 1571, is believed to have been son of Caspar, b. 1548, and some of the first Caspar's descendants do not have the 16. Thus, Caspar, b. 1571, must have been the first with it.
Jakob Yoder and Margret Stähli had sons including a Christian, b. 1697, who had older brothers, but DNA of that line does not share mutation 16 at 19, so that Jakob and Margareth were not parents of the 1742 immigrants.
You just need to identify all of the descendants of Christian, b. 1571, and you should find the parents of Christian, b. ca. 1700. :-)
Actually, that will probably be a difficult if not impossible task because the Amish were in hiding, so the records may not exist. However, if you have proof to Christian, b. ca. 1700, you can be fairly certain that Christian, b. 1571, is your ancestor.
