W. O'Connor is buried in Calvary, and we have notes that say he is Sarah's brother. We also have a record of a Michael O'Connor living with Sarah and August & Family in NYC in 1880. He is the correct age to be her brother. One wonders if "W. O'Connor" might be the same person? His grave stone doesn't give dates. But we can do more reseach to figure this out. Just not a top priority right now.
