Sabbey : sabb-bee
Sebbey: seb-bee
Sivvy: siv-vy
Eby: e-bee (This one was definitely the hardest for me to answer! I think I would probably assume e-bee, but I wouldn’t be as sure about this one as the others.)
[name]Ebbie[/name]: eb-bee

Sabbey : sab-ee
Sebbey: seb-ee
Sivvy: siv-ee
Eby: No idea; I’d ask whoever had that name.
[name]Ebbie[/name]: eb-ee?

Sabbey : sabb-bee
Sebbey: seb-bee
Sivvy: siv-vy
Eby: e-bee
[name]Ebbie[/name]: eb-bee

Generally, a double letter behind a vowel makes that vowel the short sound. That is why I chose those pronunciations.

Sabbey : sabb-bee
Sebbey: seb-bee
Sivvy: siv-vy
Eby: e-bee (only one b)
[name]Ebbie[/name]: eb-bee (two b’s together)

Two letters together make a difference to me in regards to pronunciation.
