My 5th house is empty in my natal chart but some of my natal planets from the 3rd and 4th house, are in my 5th house in my relocation chart from the location I've grown up in and now live in (again after a few years abroad) since Feb.1977, I was born in Dec.1976.
I had 3 reasonably easy births, a bit early, one premature. I can't find my relocation chart now, but I remember that it's my Sun/Cap, Moon/Cap and Mars/Sag that relocate to my 5th house. 2 sons with very Earth dominant charts, 1 son with a very Fire dominant chart, despite his Earth Sun.
The relocation chart has Scorpio on the 5th house cusp. My husband and children's father is a Leo with an 8th house stellium. I don't know if I'm reading too much into my relocation chart though and wanting to see things that aren't there, though.
For comparison between the relocated placements I've mentioned here vs. my natal chart - my natal chart is on my profile.
