Hello and thank you for helping out.
Yes, I am sure about the birthdate being 1848. That is the date listed in the 1900 US Census.
I have my great grandmother listed as Jane Rohous on my grandfathers death certificate as well as some of the brothers. I can't find information on where they married. She is listed as being from TX. I'm guessing he moved to TX shortly after the Civil War. Joseph the oldest was born in 1880 I believe.
Sam was born in Hagensport, Franklin, TX. b. 1900 d. 1969 in Houston, TX. He married Aggie May Smith in 1927. Aggie was born in 1908. I don't recall where she was born.
Joseph is listed as being from Cole county MO on the death certificate of Joseph or Allen Wells. I believe Joseph died in 1911 in hagensport, TX. Allen in 1920. I don't recall where in TX he was living at the time.
