MRS.

D. THORPE, of Myersville, Pa., and Mrs. David SPRINGER, of Salamanca.  One brother is also living, Ira DAVENPORT, of Elmira.  The funeral was held at 10 o'clock Tuesday morning from her late home, conducted by Rev. S. B. Keeney, pastor of the M. E. church of Lockwood, of which she was a member.  The interment was in the family burial ground.
