These are the names where either the gender or the expanded form was uncertain. Surprisingly, for the size of the data set I was working from, this is quite few.
| Eles | |
| Eles Aspinwall, 10Mar1567 | This could be either a form of feminine Alis or Ellice or of masculine Ellis. |
| Julian | |
| Julian Hesketh fi: Gabriell ge-t, 28Nov1600 | This is could be either masculine or feminine; in the early 17th century it's more likely feminine. |
| Ro: | |
| Ro: Hollande fi: Tho:, 21Aug1572 | This is almost certainly masculine, but whether it is a form of Robert, Roland, or Ronald, I don't know. My guess would be Robert, which is by far more popular than the other two. |
