Death of Mrs. Dwyer
Old Resident of Arkansas City Died at Her home Here.

At eleven o'clock yesterday at her home at 221 South Third street, occurred the death of Mrs. Mariah Dwyer, from general debility, at the age of seventy-nine years. Mrs. Dwyer was one of the early comers to this vicinity, having resided here for about forty-seven years, most of which time was spent on a farm northwest of this city. She was born in Ireland and moved to Canada in her childhood from where she came to this vicinity, where she has since made her home, and has made hosts of friends who will read this news with sad hearts.

One son survives her, W.W. Dwyer, with the Case company of Wichita; a sister, Mrs. Thos. Rogers, and several nieces and nephews, among whom are Mrs. P.H. Franey, Mrs. W.J. Gray, Mrs. A.B. Woolsey, Miss Mary Myers, Mrs. J.W. Nelson, Mrs. C.C. Tubbe, Frank and E.C. Rogers.

The funeral will be held at Pleasant Valley church, conducted by Rev. Ward, of Winfield and the remains will be laid to rest beside those of her husband, Harvey Dwyer, who died in 1897.

Agnes Duvall says both parents born in Ireland in the 1910 Census (Cambridge Ward 5, Middlesex, Massachusetts). Her death cert says she was born in "County Demar, Ireland". Best guess she meant Doomore, Achrony Parish, Co. Sligo, Ireland.
