I'm hoping to find someone who has knowledge of Thomas J Power, Jr and his brother Lawrence C Power who were the last, I beleive, operators of the L Power & Co, Philadelphia. They were the sons of Thomas J Power, Sr., who was born, according to WWI draft registration cards wa Sept 21, 1877 and was half owner of L Power & Co. Thomas J Power, Sr, according to the 1900 census was the son of Katherine Power. Katherine was the widow of Lawrence Power bn abt 1838, founder of L Power & Co. The draft registration cards also show Katherine's son Lawrence Charles Power's employer to be Lawrence Charles Power at a different address than L Power & Co. So it would seem he did not join his brother's at L Power & Co.
