Searching For The Shipleys Of Maryland-

Martha Carroll Gertrude Shipley

According to most of my research, my Shipley family can be traced back to Adam Shipley, who was born about 1650 in Yorkshire, England. He arrived in America in February 1668, along with nine other young men, transported by John Pawson, a merchant from Yorke, England. Adam performed his time of service, and by 1675 had received the fifty acres of land due to him under the incentive plan.
Many people claim his father was Hugh Shipley "a Gentleman grantee of the 2nd charter of The Virginia Company, 1609." I question this statement. Why would Adam need to indenture himself to John Pawson when his father was "a Gentleman grantee?"
My Great-Great Uncle Ulysses Shipley was one of the founders of The Shipleys of Maryland. He was quoted in a newspaper article (Frederick Post, Frederick, Maryland) dated September 15, 1926 as saying the family was descended from two brothers from Cardiff, Wales, who settled in Elkridge Landing, Maryland, in 1734. This obviously doesn't match the Adam Shipley story which is commonly held.
Searching the "Passenger and Immigration Lists Index, 1500's - 1900's" found online at Ancestry.com, I found several early Shipley immigrations:
Adam 1668 to America
Richard 1661 to Virginia
Robert 1667 to Port Uncertain
Robert 1670 to Barbados
Robert 1671 to Barbados
On yet another site I found a Joseph Shipley from London who sailed "Xpmas" 1635, at the age of 21.
Perhaps we'll never know the true story of the Shipleys, but in the meantime I will be keeping an open mind on the subject.
