I have a birth certificate listing "Caldwell or Coldwell Furnance" as a place of birth. Can anyone give me information on this area of Armstrong County? How close was or is it situated to Putneyville, PA? I am looking for information on Mary and John Blake time period around (guesstimate) 1825 to 1906. Any information regarding the location or names would be appreciated. Maureen Higgins Seifert moecow@aol.com
