Sorry hit wrong key. 1860 census - Millville; in the same boarding house listed below Elizabeth Chew is John Mickle 26, Clerk.
John Mickle married Lizzie A. Chew 15 April 1861 in Philadelphia.

I could find neither Elizabeth nor Margaret in the Pennsylvania nor New Jersey census in 1920.
16 April 1894 - the remains of 3 children ("who died 25 years ago" in Millville) of Mrs John Mickle were transferred from a cemetery in Millville to West Laural Hill cemetery in Philadelphia. (Philadelphia Death Certs.)
Since I could not find a record of either John or Elizabeth's birth in the New Jersey records of Births & Christenings, I included what I feel may be the possible fathers of each as recorded in the 1840 census index.
