I have received the Tyler County Marriage Records on microfilm via inter-library loan at the Texas State Archives. I will have them another week and I am willing to do free look ups for people. The reel I have is the earliest available. I believe from the 1840s through October of 1891.
You can post your requests here OR email me at JulietCMorgan@gmail.com
The Index is searchable on www.familysearch.org
so, if you can find your ancestors names and marriage dates first, it will help me in my research. I can email you back an electronic copy of the marriage record.
I have already recorded quite a few for the following surnames: BARCLAY, McQUEEN, MAHAFFEY, MORGAN, DURDIN, NOWLIN so I may already have copies of some to send.
