For a couple of hours, I searched micorfilm on Socorro, NM newspapers. In the "Local News" porition of the November 26, 1887 edition of the "Socorro Bullion", I found this short obituary of my great-great grandfather Samuel Zimmerly:
Sam Zimmerly, one of the earliest settlers of Socorro county, died at his home last Saturday evening. Mr. Zimmerly has resided in this city for a number of years, and during that time he has been activively engaged in the milling business. for sometime the disease which finally caused his death, has rendered him as invalid, and at times a great sufferer. He leaves a wife and six children to mourn his death, while a host of friends sympathize with the bereaved family.
