I'm an Orrell - no relation. Until my health went south I researched the entire Orrell surname (all variations) for many years. In fact, I found your name in my notes from many years ago.
Seems this family used both spellings - ORELL & ORRELL.
1860 NY Walter ORELL 44; Catherine 48; Eliza, Sarah, John, Walter, Emily, Emily.
1870 NY Walter ORRELL 59; Catherine 49; John, Walter, Emily, Catherine.
1880 NY Walter ORRELL, 69; Catherine 56; Walter. A Kathy Orrell is next door prob sister. - In my notes is says Walter Raymond change his name back to ORELL. My notes also give Walter Jr of Walter -Cathrine wife as Angelina Collard. I have no documentation for that.
I've found over the years that the name was spelled differently many times. My own family used ORRILL frequently back in the 1800.
BTW: I started this forum. I do not research actively anymore.
