my software only goes back to the 1700's.

It would depend on how these planets are aligned to each other. Venus and Jupiter appear that they are conjunct.
It would be interesting if Mercury and Mars were also conjunct.
All I can do is interpet what a person born under these specifics would probably be like. (for what its worth)
A person born at a time when the sun is in Gemini and the moon is in Sagittarius would likely be a jovial person, and a good communicator. Most likely would like to travel a lot.
Mars in Cancer inclines toward passive-aggressiveness , as well as a strong nurturing drive Mercury in Cancer people communicate with feeling, conveying a sensitive, withdrawn, and thoughtful nature to the people they interact with.
Saturn in Taurus says that the person will not be wealthy, or have much in the way of material things.
