Hi,
I would like to help but am a bit confused.
A marriage on 11 April 1893 between Gerhardus Jacobus Rudman (age 22) and Jessie Julia Lyons (age 19) at Uitenhage, Ellisras, Transvaal, South Africa. The consent for the marriage is given by the mother of the bride Jessie Julia Lyons - the father being dead. Is this part of your tree?
Alternatively is this the correct family -
Baptism of Jessy Johanna Lyons on 4 April 1907 (birth 18 March 1907) - daughter of James Arthur Lyons and Johanna Catherine - Jansenville, Cape Province, South Africa. Fathers occupation - Constable.
If you could specifically set out the family line it might help.
Alan
