Hi Lynn, This is briefly what I found or should say did not find. Only William Gibson that would seem to fit at all was in Hillsboro City, 1900, 50, Married, but a lodger and a RR conductor. Could find no Maude, Sophia or Byran. I looked in both Hill and Limestone counties 1880 I could find no William with a father named George. I, also, tried Byran in 1930, as that has an all name index ........ none. Sorry, I could not be of more help, if you come up with more info, I'll be happy to try again ......... remember, I may have missed someone. Good Luck, Lynette in CA
