"EDGAR ALLEN, M.D., a graduate from Jefferson Medical college, Philadelphia, who has been in active practice in this county since early in 1891, and has already won considerable distinction in his profession, is a son of John and Catherine (Dalrymple) Allen, and a native of Hunterdon county, New Jersey, where he was born April 2, 1861. He attended the common schools of Bloomsbury, New Jersey, during his boyhood, where he made rapid progress, and when about fifteen years of age secured a position as clerk in a dry goods store at Easton, Pennsylvania, where he pursued his studies of evenings in a night school, while clerking during the day. Possessed of an earnest and ambitious disposition, and determined to secure an education and become a useful member of society, he rapidly mastered the ordinary branches, and in 1885 began the study of medicine with Dr. A. L. Kotz, of Easton. Later he matriculated at Jefferson Medical college, Philadelphia, and was graduated from that well known institution in the spring of 1890. He returned to Easton and immediately opened an office for the practice of the healing art. After one year's practice at that place he removed in 1891 to St. Mary's, Warwick township, Chester county, where he has been successfully engaged in the duties of his profession ever since. Having thoroughly prepared himself, and naturally possessing many traits which mark the true physician, he has been successful in building up a lucrative practice that has aggregated over three thousand dollars in the short time he has been located here. Dr. Allen is inclined toward independence in political action, and in religion is a member of the German Reformed church. He is also a member of Pughtown Lodge, No. 369, Independent Order of Odd Fellows, and of Washington Camp, No. 335, Patriotic Order Sons of America, at the village of Nantmeal.
"On October 30, 1884, Dr. Allen was wedded to Lizzie H. Lattig, a daughter of Simon H. Lattig, of Northampton county, this State. To the Doctor and Mrs. Allen has been born one child, a daughter named Katharine Ruth, whose natal day was July 16, 1892.
"The Allens are of Holland descent, but have been natives of New Jersey
since the early days of that Commonwealth. John B. Allen, paternal grand-
father of the subject of this sketch, was a native of Hunterdon county, New
Jersey, where he lived all his life, and died at a good old age. In early
life he learned the shoemaker's trade and worked at that occupation nearly
all his days. Politically he was a Jacksonian democrat, and soon after
attaining his majority married a Miss McCullom, a native of New Jersey, by
whom he had a family of nine children. One of his sons was John Allen
(father), who was born in Hunterdon county, New Jersey, in 1818, and died
April 6, 1891, at his home on the old Allen homestead in that county. He
was a carpenter and builder by occupation, a stanch democrat in politics,
and in religion a member of the Christian church. He married Catharine
Dalrymple, a daughter of William Dalrymple, a prosperous farmer of Hunterdon
county, where he lived all his life, becoming influential and prominent.
By
his marriage with Miss Dalrymple Mr. Allen had a family of eight children,
five sons and three daughters: William H., Theodore G. and David B. are
engaged in contracting and building in the city of Newark, New Jersey, where
they reside; Charles S. is a druggist at Bloomsbury, in Hunterdon county,
that State; Dr. Edgar, the subject of this sketch; Mary E.; Elnora, died in
infancy; and Christiana, deceased at the age of twenty-three. Mrs. Catharine
Allen (mother) is still living."
