Per L&M: William Ackworth, the naval storekeeper at Woolwich's first wife (Avice Cole who died in 1643) was a younger sister of Commissioner Peter Pett's wife.
Whether or not this made her Mary Pett's younger sister, I don't know. But there was a relationship between Commissioner Pett and Storekeeper Ackworth.
