We are trying to find out about my great grandmother Beatrice Elizabeth Susannah Kathleen Muller b approx 1896 in South Africa. She married her first husband, my great grandfather Samuel Reuben Patrick Harrison in the Church of the Immaculate Conception, East London, South Africa on 15 May 1916. Her father was already dead by the time she married at 20 years of age as it was noted on her marriage cert that she had a guardian. On her subsequent marriage she noted her father as Thomas Ignatius Millar but her maiden name on her first marriage certificate is Muller so I imagine her fathers name is Thomas Ignatius Muller.
Beatrice named her son John Thomas Devine Harrison b 1921, her daughters were Patricia Rubena Harrison b 1918 and Kathleen Elizabeth Christina Harrison b 1919- all born in East London, Port Elizabeth, South Africa and all baptised at the same church as the marriage.
