The marriage of Peter InDenHoffen and Sidonia Levering was on Dec. 24, 1711 by Rev. Van Vlecq and recorded in the records of the Bensalem Reformed Church, Bucks County, PA.

Nine of the 10 children of Sidonia Levering and Peter DeHaven are shown below with birth dates prior to 1735. Peter had two additional children with his second wife, Elizabeth McNulty, a second John and an Abraham. Elizabeth died before Peter but her death date is not known nor where she was buried.

Some sources show all children with Sidonia and no mention of a second wife, this is in error.

There was an unmarried daughter, Mary, born about 1729, a daughter with Sidonia, living in 1768 when Peter died. Also a second son, John, born about 1744 with wife Elizabeth. Both Johns were living at Peter's death.
