Looking at houses and their thematic rulerships is really standard, going back to Hellenistic astrology. A good book on how traditional astrologers interpret/ed houses is Deborah Houlding, Houses: Temples of the Sky. (She is the owner of Skyscript, a major traditional astrology web site.)
One traditional view of parents is that the sun rules the father in a day birth, but Saturn rules the father in a night birth. The moon rules the mother in a night birth, but Venus rules the mother in a day birth. Then traditionally the 4th house rules the father; and the 10th rules the mother (as the wife--7th house from the 4th) of one's father.)
The connection with the 4th house and "home" here is that historically one's patrimony was determined through the male line.
