From Portrait and Biographical Album, Wapello County, Iowa (1887):
Daniel Zollars, one of the prosperous and highly respected citizens of Ottumwa, has been a resident of Wapello County for over thirty-three years and has fully established himself in the respect and confidence of his fellow-citizens. In early life he was engaged in farming pursuits, and after coming to this county purchased 330 acres of land near Eddyville, which was mostly unimproved. He there erected a steam sawmill, as it was impossible to get lumber to improve with, and was patronized by people living a great distance from the mill. He also purchased land in the city limits of Ottumwa, which he laid off into town lots and sold, the proceeds yieldig him a handsome profit, while at the same time the property furnished comfortable and economical homes to the enterprising members of the rapidly growing community. He has laid off four additions to the city of five acres, and three other additions of twenty acres each, and he still owns a farm of 100 acres in Washington Township besides 200 acres near Centerville and a valuable lot fronting the public square in Albia.
The subject of our sketch was born in Pennsylvania in 1808, and is the son of John and Frances (Hahn) Zollars. When he was four years old his parents moved to Harrison County, Ohio, where our subject was reared on a farm and lived until he came to Iowa in 1854. His parents settled about ten miles west of Ottumwa, and he lived with them there ten years, engaged in farming pursuits. He was a young man of energy and enterprise, as will be seen by the foregoing history, and in a brief time became prominently identified with the business and industrial interests of the section.
The marriage of Mr. Zollars and Miss Mary A. Duckamiller took place on the 7th of June, 1831, in Ohio. Mrs. Z. was a native of Harrison County, that State, and the daughter of Frederick and Margaret (Winings) Druckamiller, both natives of Pennsylvania. Of this union there were born seven children, only three of whom are now living: William died Jan. 27, 1872, at the age of thirty-nine years; Elmira is the wife of Isaac Millisack, of Ottumwa; Sarah J. married James Steveson, and died in Kirkville in 1860; Thomas J., born July 7, 1839, is an insurance agent of Denver, Col.; he served three years as Captain in the 4th Iowa Cavalry, being at the siege and capture of VIcksburg, and participating with his regiment in the various engagements until the close of the war. He finished his education at Wesleyan University, Mt. Pleasant, Iowa; Malinda died at the age of two years; Margaret became the wife of Joseph Harman, of Ottumwa; Emma died at the age of ten years.
Mr. Zollars commenced life a poor boy, at the foot of the ladder, and has climbed up to his present position solely by the exercise of his own native talents. In early life he was trained to habits of industry, and has never considered it a hardship or a disgrace to engage in honest labor. He has been an important factor in the growth and development of this section, and is one of the valued members of the community. Mr. and Mrs. Z. are members of the Methodist Episcopal Church, and politically Mr. Z. votes with the Republican party.
