  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 1679; 
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 
intern 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.

  He is a member of the Evangelical Lutheran Church of the 
Transfiguration, Pottstown. Dr. Casselberry is a member of 
the Benevolent Protective Order of Elks, the Ancient Order 
United Workmen, and also vice president of the Montgomery 
County Medical Society and a member of the State Medical 
Society and the American Medical Association.

  Politically Dr. Casselberry is a Republican, although he 
has never sought office and is more devoted to the duties of 
his profession than to merely partisan pursuits.
