The following is from the above book.
Emigrants coming to America and landing in the port of Philadelphia, Pennsylvania, according to Pennsylvania Archives, Second Series, Vol. 17, page 429; "List of Foreigners imported in the ship Barclay, Captain John Brown from Rotterdam, last from Cowes. Took the oath and declaration to the Government, September 14th, 1754, "Johannes Crous," which we believe to be our original ancestor in this country. The families are not listed in these registrations of the ship, but tradition in our family says that our ancestors coming from Germany had several brothers. There appears on the tax list in Philadelphia in 1780 the names of John, Christian, Henry, Jacob, Adam, Michael and Valentine Crous. These all must have been brothers as we find no other person spelling their name in the same way coming into the Philadelphia port durning these possible years of the entry of our American ancestor.
The records show that Jacob and Adam went to Cumberland County. Adam appears on the tax list of that county in 1787. Penn. Archives, Vol. 24, 3rd series, page 657. Valentine Crous appears on the Philadelphia list in 1769, hence he was probably the oldest. Christian Crous estate appears on the list in 1783, 3rd Series, Vol. 16, page 550, hence he probably died some short time before.
