We've found Jacob and wife Eva Roller had three children baptized: Maria Magdalina, Johannes, and Eliner. Grandparents were Johannes and Catarina Roller.
These entries are in Davidsburg Church Baptisms 1785-1845, New Market, VA .
We also have Johannes Rolled, no date.
Our Historian found no cemetery records with those names and suggested you check Rader's church records at the Heritage Center, Dayton, VA. She thinks she saw Roller records there.
According to the snippet above Lewis Zirkle donated the land for Davidsburg Church now Reformation Lutheran church. The Rollers may not have lived in New Market, but had their children baptized there because of the family connection?
I have priced around the cost of getting a copy of these records at several places. The library of Virginia has the manuscripts of these records. They want $25 for a copy. I've decided to order a microfilm copy from the FHL and save $20. This is a description of the records: http://lva1.hosted.exlibrisgroup.com/F/ITAU4IQ1GUUP4H2V5UGDP9LBCQVIEKT41XNLSD2UMJ3BKKCVJN-15204?func=full-set-set&set_number=005332&set_entry=000004&format=999
