Notes:

He was raised in Ireland, and married there; when he sailed for Philadelphia, he had three sons and four daughters, "whose names are forgotten."
According to David Kennedy's Bible: "There [Philadelphia] John Kennedy, my grandfather, was raised and married and had three sons and four daughters; the daughters names are forgotten but the sons were Robert, John and Alexander. Robert was drowned at sea. John died near Philadelphia and left a son by the name John."

John married Margaret ROWAN in 1733 in Antrim, Down, Ireland. Margaret was born in 1719 in Ireland; died in 1796 in Tennessee, United States. [Group Sheet] [Family Chart]

Notes:

David Kennedy's small sketch of the history of the family he sprang from, with that of his wife, Joanna:
"My great grandfather was from Scotland by the name of Alexander. He fled from that country in the time of the great rebellion (that would be the rebellion of 1715 in protest over bringing George I to the throne rather than the Stuart Pretender) to Ireland."
Note: This short sketch of my David Kennedy and the data on births, marriages and deaths which follow have been a great help establishing the Kennedy lineage. Alexander Kennedy, son of Alexander of Craigoch and Kilhenzie was probably the Alexander who left Scotland, great-grandfather of David. The genealogical authorities in Edinburgh know nothing about what happened to Alexander Kennedy; but in Scotland, they lose interest in a man when he departs for Ireland !
