I checked the FITZSIMMONS family history file. There are 7 pages of information on William Fitzsimmons, including a copy of his obituary.
In the STEFFEY family history file, there are about 50 pages of research and family group sheets from my own research on this family and from the research of other patrons. Your Nelle STEFFY was married to Albert FITZSIMMONS. Information on the family and its ancestry is there.
Please contact me if you would like copies of both files. You would need to prepay the copy cost (10 cents a page) and the postage.
