Trent Surname - by: Bean

Of all the Trent's who fought during the Anglo Boer War I have managed to confirm that all are my family in South Africa barring two.
1)
Trent A
No: 4566
Rank: Private
Notes: QSA (5) Source; QSA Medal Rolls
Unit: 1st (Royal) Dragoons.
2)
Trent James Dudley
No: 4578
Rank: Trooper
Notes: Nominal roll in WO127
Unit: SAMIF

The 1st one most likely is not related (maybe way back) but the 2nd one could possibly be. If anyone can assist with more information with them. It would be much appreciated.
