Mercury in the fourth house brings movement of the mind into home, family, real estate, ancestral memory and personal space. Home is not only a place of rest, but also an information center: conversations, books, documents, technology, internet, family stories, moving plans, repair, organizing space and constant improvement of conditions.
In a strong expression this is a person with good memory, curiosity and interest in relatives. Parents may have been intelligent, educated, reading, writing and discussing news. Love of knowledge, books, archives, a home library, family history and the wish to pass information to children may come through the family.
