I have two Michaels in my Steffe file. One was b. 26 Nov 1743 in Lancaster Co, PA, (do not know when or where he died), son of Ulrich & Anna Maria (Schrimer) Steffe. The second one was b. 16 Dec 1759 in Manheim, Lancaster, PA, d. 18 May 1850 in Manchester, Carroll, MD, son of Peter & Anna Maria (Werner) Steffe.
Do you have the parents and/or children of your Michael?
