In Sarah's natal chart (above) we see sookshmantar lord Mercury, tightly conjunct 5th lord Sun in 11th house of "Gains". Mercury occupies nakshatra of antardasa lord Rahu who in turn occupies nakshatra of sookshmantar lord Mercury
The two luminaries (Sun and Moon) also sit in Rahu's nakshatra and they, along with Mercury, occupy Taurus saptamsha...divisional chart for children.
In rashi Taurus owns 2nd house of family whilst 2nd lord Venus (in 10th) occupies nakshatra of 5th lord Sun. In transit chart (left), Rahu, in sign of Jupiter, again occupies nakshatra of Mercury.
