What about for first names ending in 'a', what would the first son be called?

The examples given :
- Gota Jaab
- Sizha Epocan

Would the first son be :
- Gota'a Jaab
- Sizha'a Epocan

or

- Got'a Jaab
- Sizh'a Epocan

Or maybe does the apostrophe just go after the name, like

- Gota' Jaab
- Sizha' Epocan
