I've been experimenting with my thermostat the past couple of weeks to
see how I can save energy. I've noticed that if I keep my thermostat
at 67 degrees my boiler will cycle every hour or two to maintain the
temp - but if I set my thermostat to 66 degrees it will cycle every
4-6 hours. It's been around the 32 degrees outside all week. Is there
a natural temperature that a house can hold for longers periods?

Of course. It's the point at which heat gain (from the heating system, the
sun, appliances, lights, mammals -- you, your family, your dogs and cats)
balances heat loss (from conduction to the soil, radiation, convection, air
infiltration, etc.). It varies from one house to the next, and from one day to
the next for the same house, because the factors influencing both gain and
loss are dependent in part on the weather.

If so, how can I raise that temperature?

By reducing heat loss. The most effective methods of doing so are insulation,
weatherstripping, storm windows, etc.
