Keerl, Henry (1755-1827).

Henry Keerl was descended from an old Bavarian family. He was born in the town of Mainbernheim, thirteen miles from Wiirzburg, in the year 1755, the only child who .survived infancy and was educated by a wealthy uncle. He completed his medical studies at Gottingen University and obtained a commission as surgeon in one of the He.ssian regiments, which were being hired by the British Gov- ernment of the petty German poten- tates to aid in subduing the rebellious American colonies. But it was des- tined that he should not see his native land again.

After the defeat of his Col. Von Rail the privates and non-commissioned officers were sent for safety to the interior of Pennsylvania. The officers peti- tioned to be permitted to accompany them, but were sent on the sixth of January, 1777, to Baltimore, where they were paroled.

Dr. Keerl spent some time traveling through the country. With a friend he visited the Carolinas, where family tradition asserts they "were solicited to remain and marry among the rich widows whose husbands had been killed in the war." But having form- ed agreeable acquaintances and find- ing a favorable opening in Baltimore, he finally settled and practised, about 1782, and in connection with his profes- sion kept a drug, instrument and glassware store at the "Sign of the Golden Swan, upper end of Market Street, New Congress Hall."

He early became a member of the Medical and Chirurgical Faculty. He died July 6, 1827. He was twice Vol. II-5

married, first to Anna Maria Myers, of Baltimore, afterwards to Margaret Kandel, of Frederick, Maryland, and left numerous descendants. His life was spent in the habitual practice of virtue and piety. E. F. C.
