I checked some books I have looking for your Wollets and found the ship arrival record you refer to for the Richard and Elizabeth in 1733. I would imagine that Johannes Wollet, age 38, and Anna Margaretha Wollet, age 24, were probably husband and wife based on the other records I have found for them.
They show up in baptismal records in Montgomery County, PA, having a daughter, Margreth, baptised on 9 May 1736 where they are listed as Hans and Margreth Wolet. (New Goshenhoppen Reformed Church, Upper Hanover Township)
Hans and Anna Margretha Wollet later show up in the records of Jordan Lutheran Congregation in South Whitehall Township, Lehigh County, where their son Georg Adam Wollet was born 26 October 1742 and baptised there.
Hope this helps some.
