This is based on her public birth certificate which has no time posted as Mrs. Cruz was born at home on November 23, 1934 in Baltimore, Maryland. The time is just an approximation. Her birth as many Americans will remember became an issue in the 2016 Election because it was question by then candidate-Trump whether Senator Ted Cruz was eligible to be the lawful President of the United States. Breitbart News, run then by Steven Bannon said it was moot. Read here for more.
The Map of Eleanor Darragh Cruz
Mrs. Cruz has a cardinal natural disposition suggesting that she is very action oriented and does not really let the grass grow under feet; she takes charge of situation and wants it to be successfully carried out. That works well for a woman whose career was a nurse, as does her Ascendant in Cancer, a naturally mothering sign but Uranus in the Tenth house, that career was quite eventful — including having to move to a foreign country with her first husband and again with her second. But as Uranus is also in Aries, she managed that with aplomb and little complaint.
While her son, Senator Cruz, was a great student, his mother probably was not, with Neptune in the Third House and would prefer working to learning, getting hands on experience and learning from mentors and not teachers. While this chart was erected for sunrise and may not at all be correct, Neptune in the Third house also makes her rather eccentric and out of the norm, and conjunct nearby Mars would naturally encourage her son to his loftiest dreams, not even once thinking them ridiculous or fantastic.
Finally, she has a preponderance of planets in Sagittarius, the great traveller, in the Sixth House, so perhaps this wild guess chart is not as far off as one suspects.
