It's called derived houses, derivative houses, houses within houses and a few other things.
Your first child is the 5th House, the second is the 9th House (the fifth from the 5th), your third child is the 1st House (the fifth from the 9th).
Step-children are the 11th House. The 2nd born step-child is the fifth from the 11th House.
If your parents are the 4th House, then their parents are the fourth from the 4th, or the 7th House. So your great-grandparents would be the 10th House.
A marital partner's resources are the 8th House, but only for your first marriage. Your 2nd Marriage is the 9th House, so your 2nd spouse's assets are the 10th House.
In a Mundane Chart, the 10th House represents the government, leaders, etc etc. Which house represents secret enemies? The 9th House because it is the twelfth house from the 10th House.
If the 7th House represents your spouse or your business partner, then which house represents their secret enemies? The twelfth house from the 7th House (so it's the 6th House).
If your father is the 10th House, then his second wife would be the 6th House, not the 4th. That makes the 6th House the step-mother.
So, who are the secret enemies of the secret enemies? The twelfth house from the 12th House which is the 11th House.
If the 10th House is your father, then which house is his brothers and sisters? The third from the 10th, which is the 12th House.
When you delineate a chart, you need to delineate all of the house meanings. So if you have Saturn in the 4th House, the 4th House represents many things, including your life in your twilight years.
So what does Saturn in the 4th House mean?
Well, what does Saturn mean? Saturn means many, many things. Are you going to be organized and disciplined in your old age?
No, that isn't what it means. It means ill-health, loneliness or living miserly. How do you know which? Well, what house does Saturn rule in the chart?
If Saturn rules the 2nd, then you'll better start saving all the money you can now and retiring as much debt as possible, or you'll end up eating cat food and joining the Gray Panthers. If it rules the 6th House, then invest in a pharmaceutical company, because your health will be bad.
You'd be surprised how many baseball and football players smoke, whether its tobacco or marijuana.
I can't say definitively that she is or isn't using drugs and/or having an affair, but those are two very good reasons to lie to the police, which would cause the police to insist upon polygraph tests. She might be bi-sexual, and the affair is with another woman.
Venus is at 18 Can 35 and Mars at 28 Leo 39 and that's 40 degrees and that is a nonagon, which means some kind of test, perhaps a loyalty test or something. It's with a mere 4' of arc. That is just too much to be a coincidence.
It's a different world now. It's reality TV and Talk-Show Nation. 20 years ago, a missing child was local news, not national news. I know from other recent incidents of missing children, the police were swamped with calls from all over the country by people just wanting to talk and vent, people just wanting to express an opinion and people just wanting to explain their theory of what happened.
The police don't have time for that nonsense.
Police also withhold details because there are a lot of sick people who will confess to crimes, even though they didn't commit them.
I try to stay away from media reports (very easy since I don't have a TV) so it doesn't prejudice my reading of a chart.
