Unfortunately, this is impossible to calculate because we don't have records that far back.
The current theory: about 1 degree Celsius I believe.

About 1.1°C (2.0°F). The 2006 global aveage temperature was 14.77°C, in 1806 it was 13.65°C.
There's more data available for 2006 and it's possible to work out very accurate averages. There was a lot less back in 1806 but the British have tempoerature records from all parts of the world dating back to the 1600's and using this info it's possible to get a pretty accurate figure.

Around 0.7 degrees in the last century, but I don't know at 2 centuries. Sorry

Around .6 - 1.1 degrees, but we can't really know because there are no accurate temperature measurements back then. We rely on observations from tree rings and glacial ice, but there's no way to tell if we're making the right observations about these things because there's no absolute data to compare the results to.

There are no reliable sources dating that far back.
But estimates would suggest a figure of 0.7-0.75 C rise in the last century and half the figure in the previous century.
That makes it 0.7+0.35 = 1.05 C.

Less than a degree.

I DO NOT THINK THERE ARE RELIABLE RECORDS THAT GO THAT FAR BACK.
