Yes, there is much evidence of ancient volcanism on our moon. One good place to start your search for this information is the Marshall Space Flight Center's Marshall Space Flight Center page. At the bottom of the page, enter "volcanoes on the moon" (without the quotes) into the "Search" box. This will return a long list of sites with information about volcanoes on the Earth, moon, planets and planetary moons.
Some of the more informative sites include:
