When I first began a study of the Alliance Furnace (1790-98 Jacob's Creek, Westmoreland) I attempted to find out the names of the the workers at the Furnace by referring to the 1790 Census. I checked the index for same at the local LDS center and discovered that the enumerator had listed the employees under the name of one of the partners (William Turnbull). As I knew that only the head of the household was named in the 1790, I took the number of souls listed as gospel, and let it go at that. The LDS index counted 26 males over 16 and one slave. I recently had an occasion to view the actual page itself. The original listed only 24 males over 16. The next listings, under separate names, showed that those named were black. Since they were free blacks, they were not listed as slaves, but researchers should note that their color was deemed important enough to designate them as such. More importantly, the LDS compiler ignored the actual listings and combined the over-16s and! thus wiped out this data. Listers should take notice that the LDS indices might be wrong, and that the actual pages are the ultimate truth. To check if blacks in other counties were so listed, I checked Allegheny county and found they were so treated. Allen D. McCrady
