I have lived in this area and never in my 64 years heard any part of Blackstone called Waterford--so perhaps like many small areas of towns that had nicknames it has gone by! I had ancestors born in Partridge Field, Ma. and it took me quite a few years to locate where that was! Records state my great-aunt was burned in Hayward Field and died the next day--in 1901--it is just an area in the town of Milford. Old towns had lots of areas in them with various names especially here in this area of Massachusetts. Helen
