The Penrose family of Philadelphia were socially prominent and were High Church protestant Episcopalian. Rebecca's brother, Isaac Pennock, Jr., married Harriet Penrose. Further, Harriet Penrose's brother, James Penrose, married Marian Pennock, youngest daughter of Isaac and Martha Pennock and therefore Rebecca's youngest sister. James and Harriet's son, Charles Penrose, thus entered the family circle as cousin to Dr. Charles and Isabella Lukens. In 1859 he entered into the firm as head clerk. |
