Lester, Nathaniel was the son of John C. Rittenhouse and Leah Gehr. Margaret was one of his and his wife, Mariah Painter's children. Margaret (born March, 1873) was appointed guardian of the minor children after their deaths. Margaret married Frederick Griel in 1890 and they had one son that I know of, Frank born in April 1893. My notes show that Frederick, born in March 1859 was the son of Jacob Griel and Anna Conrad. Hope this helps. Dyanne PS It is nice to know that someone read my posting. John and Leah have been a brick wall for many years.
