E. C. HOLSINGER IS NO MORE
Passed Away at 2:40 p.m. Tuesday in Albuvuerque [sic - Albuquerque] New Mexico, Where He had Gone in Search of Health.
A telegram received by Miss Leah Holsinger Tuesday evening brought the sad news of the death of her brother, E. C. Holsinger, ag 2:40 p.m. at Albuquerque, New Mexico, whither he went about a month ago in company with his wife, in hopes that the change of climate would do him good.
When he first arrived there he seemed benefitte bu the disease from which he had been suffering for several years, consumption, had too strong a hold upon him. The remains will be brought back to Salem for burial, and will arrive the last of the week.
Elmer C. Holsinger was born in Kansas City, Mo., Aug. 12, 1871. Later the family moved to Kansas, and Elmer, when only a boy, learned telegraphy, and got his first assignment at Virgil, Kansas, in the employ of the atcheson, Topeka & Santa Fe Co.
Later he was tranferred to New Mexico, where he stayed about one year, and as he enjoyed excellent health there, he thought that the climate would again restore him to health after he began to fail here.
He was married in June, 1898, to Miss Carrie Veatch, who survives him. The father, J. Holsinger, and brother, Fred, are in the mines, the former at Glendale and the later at the Copperstain mine, and a sister, Miss Leah Holsinger, in employed in the Salem postoffice.
In 1891 he came to Salem where he worked in the Postal Telegraph office. He afterward accepted a position at Astoria in the emp;loy of the Western Union Co. In 1895 he returned to Salem and took charge of the Western Union Office here, which he held until Oct. 5th, when he resigned to go away.
Elmer Holsinger was a man universally respected and liked, and his untimely death affects many of Salem's people with a sense of personal loss. The sympathy of the community will go out to his young wife and his relatives in thier bereavement.
He was a member of the order of the Maccabees, and his funeral will probably be conducted under the auspices of that order.
