DR. CLARENCE MARMADUKE CASSELBERRY is one of the most prominent of the younger members of the medical fraternity of that section of Montgomery county adjacent to Pottstown, where he was born October 5, 1875. He is the son of Marmaduke Burr and Amanda Elizabeth (Yocom) Casselberry, the former a native of Montgomery county and the latter of Berks county. The couple had four children, one son and three daughters, namely: Gertrude (deceased), who was the wife of Dr. D. Walter Spence; Ella, wife of Ellsworth Lincoln Edwards, of Pottstown; Dr. Clarence M.; and Mary Elizabeth, wife of Robert J. Scott, of Pittsburg, Pennsylvania.

Marmaduke B. Casselberry (father) was a general merchant, subsequently a tanner, and still later a banker in Pottstown, of the M. Burr Casselberry & Company’s Bank, previously known for many years as John W. Casselberry & Company, bankers and brokers. The past ten years or more he has lived retired. He and his wife are Lutherans. He was among the emergency men in Pennsylvania during the Rebellion, when the state was menaced by the Confederate forces for a short time. Mr. Casselberry is an active Republican and votes the ticket of that party. He was member of the board of health of Pottstown under the administration of Burgess Jesse Evans.

Richard Casselberry (grandfather) lived in the central part of Pottstown. He came originally from Evansburg, a few miles above Norristown, the ancestral home of the family. He was a farmer by occupation. He married Elizabeth Miller and they had a large family. He was prominent in politics and an active worker in the Republican party.

John Yocom (maternal grandfather) was a native of Berks county, conducted a general store at Amityville, and was also engaged as a farmer. He removed to Pottstown and entered the iron business, in which industry he was interested until the time of his death. He died suddenly while going to a fire near his home on High street, when he was about forty-eight years old. His wife was Hannah Caroline Miller. They had several sons and daughters.

Moses Yocom (maternal great-grandfather) was also a native of Pennsylvania, being of Swedish descent. The founder of the Yocom family in this country was Peter Yocom, who came from Sweden in 1638 and settled near Philadelphia. His children were: Peter, born in 1678; Moses, born in 1879; Catharine (unmarried) born in 1682; Charles, born in 1683 in Philadelphia; Swan, who settled a few miles above Philadelphia; Jonas, who was the head of Dr. Casselberry’s family on his mother’s side; Andrew; John; and Julia, who married a Morgan, one of the Welsh settlers of that vicinity. One of the Yocoms married a Miss Ball, who was a sister of Washington’s mother. Peter Yocom, the founder of the family, is often mentioned in William Penn’s letters.

Dr. Clarence M. Casselberry was reared in Pottstown and attended the public schools for some time. He then prepared for college at the Hill school, Pottstown, and then entered the University of Pennsylvania, being graduated from the medical department of that institution in 1897. He became an interne at St. Joseph’s Hospital at Providence, Rhode Island. From that place he went to Boston and practiced in that city four years, being connected with The Boston Emergency Hospital there, as attending surgeon. He returned to Pottstown in 1902 and opened an office there, and is now successfully engaged in the practice of medicine.
