  In this paper we introduce and investigate moment generating Stirling numbers
of the first kind, "`MSN1"'. They are inverses of MSN2's, which make the
representation of the moments for a lot of statistical distributions in closed
formulas possible. Both MSN1's and MSN2's are related to the r-Stirling
numbers, and extend their properties to any real third parameter. If the third
parameter is a nonnegative integer, r-Stirling numbers can be converted to
MSN's and vice versa.
