I am searching for information re: John Anderson Logan, an engineer, born 10/Sept/1826 in Edinburgh. He was in the United States by 1860 and may have been before. He may have a brother, Daniel born 7/Feb/1835, died 10/Feb/1869. Both these men lived in Syracuse or Versailles, Missouri. John went to Oklahoma in 1906 and lived there till his death in June 24, 1873. Family members used to correspond with family in Scotland, but all addresses are gone and family members dead who could supply further information.
Thank you so much for assistance.
