"In 1801 a village charter was obtained for Troy, and here two brothers, Asa and Warren Kellogg, settled a few years later in mercantile pursuits. They had established themselves as leading wholesale merchants of that section, when in 1815 their nephew, Day Otis Kellogg, came to be their apprentice. [...] In 1827 Mr. Asa Kellogg retired from the mercantile house in Troy, of which he was the senior member, and his two younger brothers, Warren and Alexander C., continued the business, inviting their nephew, Day Otis, to join them the following year."

"At half past 8 o'clock yesterday morning, after a long and painful illness, in the 59th year of his age, Mr. ASA KELLOGG, merchant of the firm of Kelloggs & Co., of this city.
"Though disease had for several months disabled him from the more active pursuits of life, and though his decease had long been expected, yet his death will afflict his surviving family and relatives with an anguish which no earthly balm can soothe, and cause a chasm in this community which must be long and deeply felt. One of the oldest and most extensive merchants in this city, his efforts have eminently contributed to that high and honorable character, upon which our rising and advancing prosperity in a great degree depends. Kind, amiable, and liberal in his family, their loss is without remedy, except in the sanctification, the support and the consolations of an Almighty Father. Highly and unerringly scrupulous in his honor and integrity, his life is a worthy example of honesty, and furnishes an eminent illustration that
"'An honest man is the noblest work of God.'

"The relations, friends and acquaintances generally of Mr. Kellogg and of his surviving family, are respectfully invited to attend his funeral to-morrow afternoon, at 3 o'clock, from his late residence, No. 102 Third-street."

"Among the most curious lots in the cemetery is the Kellogg lot. It is said that there are no descendants of this family, which came from Norwalk, Conn., living, and one might well believe this after seeing the lot. Literally dozens of graves are marked with stones. There are large stones and small stones, and they stretch back and still back until a considerable portion of the burying ground is taken up with the marks of the last resting places of this numerous family. Can it be that this family is extinct? That all lie here? Could some great calamity have touched them, and death laid his cold finger upon them all in rapid succession? Or is it possible that in the hour of death when far away the thoughts of all turned back to Troy, and the last requests were to be buried in Old Mt. Ida. No answers will ever be given to these questions. The graves will remain silent witnesses of their silent occupants, that branch of the Kellogg family has passed our of mortal ken."
