ULRY, ULERY, ULEREY, ULREY Cousins???

I am descended from EMANUEL ULRY who married Lucinda WINGET (also seek WINGETs) in IL, mid-to-late
1800s. They had JAMES BUCANAN ULRY as one of their children. I would like to go backwards further with
EMANUEL to his parents,and beyond. Does anyone know (for certain)if Emanuel (called Manuel,also) was brother to PETER ULRY of IL? I believe they were, as lived near to each other, and both came from PA before, from the Schulykill area. Any info greatly appreciated. See you here on these boards! thanks so
much, leah
