Answer:
They were both places of religious tolerance.
Explanation:
Lord Baltimore refers to the proprietary governor of the province of Maryland.
Lord Baltimore established the Maryland colony in 1632, in response to the discrimination against Roman Catholics living within England during the period of the European wars of religion. The English Catholics were being discriminated against greatly by the Roman Catholic church in England.
The colony of Maryland was named after the Queen Consort known as Henrietta Maria of France, who was also a devoted catholic.
Also, the colony of Pennsylvania was founded in 1681 by William Penn when he acquired (obtained) a land grant from King Charles II of England, so as to provide refuge for the Quakers based on religion tolerance.
Hence, what the colonies of Maryland and Pennsylvania had in common was that, they were both places of religious tolerance.
