Underwood, who lived in England for a number of years, was an "eminent merchant of New York City" and traveled often. Her husband died on January 7, 1869, in
Yonkers, New York. Rosalba died at age 75 on November 15, 1874, in
Bustleton, Philadelphia, in Pennsylvania. She was buried at
Woodlands Cemetery in Philadelphia. ==References==
