I am doing a project to see how many times a planet passes in front of
another one and believe there to be 122 occurances like this in the 6000
years between 3000bc and 3000 ad and was wondering if any have been
observed.

I Googled for planetary occultations and the second entry was
http://www.go.ednet.ns.ca/~larry/planets/occltlst.htm.

It would probably not been seen before the telescope was used ands most
occur in daylight however it looks like the Mercury in front of Saturn 9th
December 1808 at 20h approx and Venus in front of Jupiter 3rd Jan 1818 at
about 22h may have been seen.

Both given there.

does anybody know if these were seen and if my dates are correct
The next 3 seem to be Mercury Saturn on 15 September 2037 at about 22h ,
Venus Jupiter on 22 November 2065 in daylight at about 13h and Mercury Mars
11 August 2079 at about 02h

No, yes, yes.

The first entry also gives dates :
