manded the naval forces of that country that brought about independence (1846). 

 After that, when Garibaldi came to the United States, De Rohan went to Chile 

 and became admiral of the Chilean navy. He took an active part with Gari- 

 baldi in the unification and independence of Italy. At this period he was not only 

 made admiral of the Italian navy, but furnished money to buy 3 steamers, 

 the nucleus of the Italian fleet. During the siege of Rome, De Rohan commanded 

 the marine division and supervised the artillery fire. He spent many years in 

 England, where he became interested in the workings of the British naval reserve, 

 in which he was commissioned a commander by the admiralty. He was anxious 

 to fight for the Union in the American Civil War, but was restrained by fear of 

 being brought under the command of his brother. He was possessed of a large 

 fortune when he entered the Italian navy, but lost it all because the Italian gov- 

 ernment refused to reimburse him. He sought redress in diplomatic circles, but 

 all to no purpose, and he died in Philadelphia, the city of his birth, a poor man, in 

 April 1891." 



The trait of nomadism was in the father also, Bernard Ulrik Dahlgren, 

 born in 1784. He was graduated from Upsala and was an adventuresome traveler 

 at an early age, making frequent expeditions to hyperborean regions. At the age 

 of 20, having become involved in an attempt to disseminate republican principles 

 at Gefle, he was obliged to flee from Sweden and his property was confiscated by 

 the Crown. After traveling extensively and incurring much hazard, he finally 

 embarked from Spain for New York, where he landed December 1806. He was 

 made Swedish consul at Philadelphia and held that post until his death. He was 

 well known as a merchant of ability and great integrity. His judgment was clear 

 and impartial, so that it commanded great confidence, and his arbitration was 

 accepted as conclusive. He was a man of herculean stature and strength, being 

 6 feet 4 inches tall and well proportioned. 



Father's brother, Sir Carl Adolf, was graduated at Upsala and was made 

 a subphysician in the Royal Navy in 1797. He left the navy in 1800, but upon 

 the outbreak of war in 1808 he offered his services to the government. He was 

 appointed staff surgeon to the army of Finland, in which capacity he served until 

 the close of the war. Thereupon he reentered the navy and thereafter held posi- 

 tions as court physician and field surgeon in chief to the army. He was created 

 a knight of Wasa in recognition of his long and eminent service. He died at Stock- 

 holm in 1844. His son, Sir Johan Adolf, was the author of various dissertations 

 on chemistry and medicinal botany and a "discoverer in the domain of practical 

 chemistry." He also was created a knight of Wasa in recognition of prolonged 

 and useful service. In 1871 he resigned the directorship of the Royal Military 

 Hospital in Stockholm and after that led a retired life until his death in 1876. 



Father's father, Johan Adolf Dahlgren, born at Norrkoping in 1744, was 

 educated by private tutors. He then studied chemistry and pharmacy and became 

 a protege* and friend of Linnaeus. He matriculated (1764) at the University of 

 Upsala and was graduated with the degree of doctor of medicine. He was a man 

 of great activity, a skillful physician, and a voluminous writer on medical subjects. 

 In 1789 he was named chief physician of the province of Finland. He died in 1797. 



Mother, Martha Rowan, was "richly endowed with the best qualities of head 

 and heart." She had a special taste for designing, and her son often said that he 

 inherited from her his inventive faculty. 



Mother's father, James Rowan, was a Revolutionary soldier, who served 

 as commissary in General Lacy's brigade and sustained heavy losses in his support
