Mrs. Sidney M. Van Wych Sr. is Dead at Seattle
President of Jefferson Davis Chapter, Daughters of the Confederacy, Dies
Revered for Charity
Was Host of Many Magnificent Functions During the Exposition Period

In the midst of the preparations for the dansent, their annual function given to raise funds to carry on their charitable work, word was received yesterday by members of the Jefferson Davis Chapter, Daughters of the Confederacy, of the death Friday night in Seattle of Mrs. Sidney M. Van Wick Sr., president and one of the organizers of the chapter. The news has cast a gloom over this city, where Mrs. Van Wyck was well known and beloved in an unusually wide circle of friends, and will also be a cause of much regret throughout the United States, her work with the national organization of the Daughters of the Confederacy having had a far-reaching influence.
Charity Still Benefits
The news of her demise was not made public as soon as received here, although members of the chapter and personal friends of Mrs. Van Wyck were apprised of the fact. It was determined in spite of the loss to the chapter to have the annual fete carried through, the charitable purpose for which it was planned being sufficient excuse for not having it called off at the last moment. Out of respect for the death woman, however, those of her chapter who had had large parties retained their tables at the the [sic] dansant but did not appear.
During the last few months Mrs. Van Wyck had been visiting her son-in-law and daughter, Mr. and Mrs. J. D. Peter, in Seattle, and it was at their home that her death occurred.
Four Children Survive
Mrs. Van Wyck is survived by two daughters, Mrs. J. D. Peters and Mrs. Austin Brockenborough Chinn, and two sons, Sydney M. Van Wych Jr. and Dr. Dr. Crittenden Van Wyck. Another daughter, Miss Laura Van Wyck, was killed several years ago in a steamer wreck off the Northwest coast when she was going north to visit Mr. and Mrs. Peters in Seattle.
During the exposition year Mrs. Van Wyck was indefatigable in the work of the Daughters of the Confederacy, and it as the Jefferson Davis Chapter, of which she was president, that was host at the many magnificent functions given at the exposition in honor of the distinguished Southern visitors to this city.
