carried to the fight. And in later life we find the three older brothers active in the 

 Revolution, on sea or land, in some of the most hazardous occupations. 



Unfortunately nothing is known of the maternal side except that the mother's 

 father was a sea captain. The father was at the siege of Louisburg, but was 

 ordinarily a tailor and later a lumberman. 



Love of the sea was marked hi this fraternity; the lads were taught to sail a 

 boat by their father. 



It is clear that Jeremiah O'Brien is a typical hyperkinetic. "Into whatever 

 undertaking he enlisted he threw his whole soul"; he was outspoken and fiercely 

 patriotic, of a high sense of honor, a man of "that temperament which is sus- 

 ceptible of high excitement, constitutional ardor, spirit, full of fire." x "By tem- 

 perament he was impulsive almost to the point of rashness and, in action, particu- 

 larly when thoroughly aroused, he was impetuous and irresistible as the raging 

 torrent exhibiting at such times a forcefulness of character which under ordinary 

 circumstances was not apparent to the casual observer." "Outspoken he was 

 and fear of consequences was never, so far as the author has been able to gather, 

 allowed to bridle his tongue when once indignant feeling or great thought throbbed 

 in heart or brain and pressed for utterance, and individual and aggregate of indi- 

 viduals found the same when once Captain O'Brien felt his keen sense of justice 

 outraged."
