I probably would have read this chart using 7th house as husband's house and 10th from the 7th as specific quesited signifying house (ie, the 4th whole sign house of the chart under Virgo) for the mother-in-law. However, I cannot delineate this specific chart because of my belief that the SN in the ascending sign of this chart(Gemini) renders this chart unreliable for delineation.
