Why did the British never establish any titles of nobility in the new world. For instance, why was there never a Duke of Pennsylvania?

There were attempts. John Locke (yes that one) wrote "The Fundamental Constitutions of Carolina" in 1669. It essentially was written to prevent any form of democracy from arising in the Carolinas. It would have created a landed aristocracy had it been fully implemented. You can read it here http://avalon.law.yale.edu/17th_century/nc05.asp.

However, in its early days Carolina grew very slowly. The new rules put forth by the constitutions were not very popular, and were largely gone by 1700, and they were never ratified to begin with. Part of the reason is that the Lords Proprietors did not take an active role in developing Carolina, and the settlers preferred the Royal Charter which was more flexible in its allowance for government.
