I had been doing some cemetery searches of some area cemeterys for the Fenstermacher of which I'm descendant. Not sure if its the same Samuel or Lydia Fenstermacher but its about the same period. Did a trip to Methacton Mennonite Cemetery in Worcester, Pa in Montgomery country not far from Pottstown. And buried there is Samuel Fenstermacher 12/30/1809 - 8/10/1882 and his wife Lydia Fenstermacher 3/26/1818 - 4/4/1870 along w/ Samuel and his Wife Lydia are buried five of their childrenLau? the first name was unreadable except for a letter or two was one of their children, another was Adelaid Fenstermacher she died 11/5/1867 8yrs 17 days, an INfant son Fenstermacher 12/14/1852 , Catherine Fenstermacher - 5/23/1850 she was 10 yrs and some days, and last was Annie M. Fenstermacher - 1848. Havent found the other daughter you mentioned and not sure if this is the same two but its in the same area and around the same time. Hope this helps out and if your a Fenstermacher cousin would be interested in sharing some info.
