I'm not at all sure what information you're looking for about Lassiter, but I check the Jeffco Gen Soc's tombstone inscription book and found 10 of them who (just skimming) seem to connect to a William Lassiter. All are buried at FRVF, which is Farrar - Valley Falls, Cem. Are these the folks you're looking for? Or did you already find what you needed? I found one Lassiter marriage (Paul T to Mrs Mildred Pond) 11/3/1927, and a bunch of folks named Lasater and Laster. Does any of this information interest you? Jan
