In the household of John & Jane THOMPSON, in 1860, in addition to Jane’s mother, Margaret ALLEN, was a girl named Mary ALLEN, age 18. At present the relationship is unknown, but this implies Mary was born in 1842. A transcription of the records of the Methodist Church Williamsport Circuit Station, Lycoming Co., PA, mentions a baptism of a Mary ALLEN, on 23-MAY-1858, and that she was born, 12-AUG-1842; she resided in Loyalsock Twp., at the time of this baptism. [1769] Looking for Mary in the 1850 census, the best match is a Mary ALLEN who was the daughter of Abraham & Emily ALLEN, who lived in Williamsport that year. This suggests the possibility that Abraham was a brother or cousin of John ALLEN (Jane’s father). Find A Grave Memorial# 16125993 for Abraham, links to daughter Mary Allen HENNINGER, Memorial# 131982205. The birth date given there is 17-AUG-1844. [1498] Her husband was Isaac HENNIGER, a Civil War veteran, b. 1842, d. 1929, Memorial# 122619459. He apparently remarried, as his wife at the time of his death was named Elizabeth.

Another link implies that Emily ALLEN’s maiden name was THOMPSON (Memorial# 16126001). This is confirmed by the death certificate of Emily’s daughter, Sarah Jane ALLEN (d. 27-MAR-1909) - Memorial# 16126017. However, as yet I find no connection to John C. THOMPSON.

The 1860 & 1870 census for John & Jane show a Margaret ALLEN in the household, who is believed to be the mother of Thomas B. ALLEN Sr. who is believed to have had a sister named Jane. [162], [679]
