There is a very useful site here in the UK run by a gentleman called Rodney Hall that has many useful genealogical links. The site is http://www.rmhh.co.uk/ One of the links gives an instant converter of old sums into today's equivalent. Your 1750 figure of Pounds 200 would, at least in the UK, now be about the equivalent of Pounds 21,000 in purchasing power terms. I guess that that's about USD 34,000. Hope this helps. Regards.
