Hi LibraGirl, thanks for your support!
What is your actual birthdate info to construct a chart?
Typically Capricorn would follow your Sag, possibly picking up part of your second and third, while Cancer would pick up from your eighth house.

It sounds like you have Intercepted Houses/Signs.  We were talking about this the other day on here: http://www.astrocreepsandtarotfreaks.com/general-astrology/intercepted-housesplanets/

And it's like a "room within another room".  I read that description somewhere, I can remember, but I think I posted it on that thread.  The signs Pisces and Virgo aren't ruling any of my houses... Hope that helps. 

Absolutely Kat! I always called in 'shared space' LOL - like having a roommate.

Sharing houses.  Yeah I see this alot , especially when I am doing Placidus or other "unequale" house readings.  The house will always have a Ruler (sign of cusp) and Co-rulers.  For example, Drew Barrymore. She has in her 7th hose of Relationships, both Sag and Capricorn.  Wich tells me that when it comes to relationships, She is drawn , at first, to light open cheery expansive playful and then, about halfway through, they turn serious and traditional(capricorn). 

Antoher example, Alanis Morissette.  Her rising Sign is Capricorn, so you wold figgure that she would be all serious and concrete and business like, but that is not the case. Ascendant itself is in Capricorn, wich explaines her rather "goatish in a cute way" Appearance.   But then there is mostly unconventional Aquarius followed by romantic dreaming Pisces.   

If you wish to use just the cusp signs, that is fine. Does get about 75% right and is good enough for a down and dirty report.

Read the sign on the leading cusp to be "Initallly" then followed by traits of other signs through the house

Could somone pester me to remind me to blog this subject? KTHNXBAI
