I am from the Greenville area and was living there during the time mentioned. There were two brothers who were OB/GYNs, J. M. and J. D. SMITH. They were in practice together. If you would like more info (address/phone), please contact me at DMPringle@sc.rr.com

Could that J. L. possibly be one of the initials above? I don't seem to find or remember a J. L.. Could it be J. D.? That might be a typo that you have???

Hope this is a help.
