I was "sweeping" the 1880 census for Lycoming County and McKean County PA last week and recorded the Stroups there. I know one of you had asked about Lycoming County a while back, so I hope this will help you! By the way, my library doesn't have the complete Lycoming County records for 1880, only from p. 394 on, including Washington Twp, Brady Twp, Woodward Twp, Wolf Twp, Picture Rocks Boro, Anthony Twp, Shrewsbury Twp, and 1st 2nd & 3rd wards of Williamsport.
