On a recent trip to Il.,I got copies of the Naturalizations of Peter Christian Yepsen,1884, H. Casper Yepsen,1881, and Christian Yepsen,1884.I also was able to positively identify P.C. and his wife,Anna. She is not the one I had identified previously.The Anna listed there was the wife of Christian, and they are both buried in Ohio,Il.I believe that P.C. and Chris shown here may be brothers. If any one has these men in your genealogy,Please email me.I would love to share my info. P.C. had a son named Christian,also,he was my grt grandfather.
