Yup, he's got Sun in Cancer. Just like everyone else born July 17th. For a more accurate read of the unique individual that he is, the placements of ALL the planets, not just the sun, at the moment he was born must be taken into account.

The Moon rules Cancer, and Ivor's Moon is in Libra. His Neptune, too. Libra is the Scales, here to learn/practice/showcase the delicate art of balance in relationship. And Ivor is a born diplomat -- just read through a few of his posts here. He's a good listener, a caring counsellor and a very pleasant person to have a rip roarin argument with! (said Aries Sun   hee hee!)

Ivor is more Libra than Cancer, from what I can see! And that's why I've dubbed him Sir Libra. HIs Libra Moon rules that Cancer Sun .... and that's more than enuf of an astrology lesson for one day!
