The root problem there seems to have been with the surnames. The parents would have been well aware of that having plenty of experience themselves. The only option would have been to change their own name first. The fact they haven't suggests that generations of them have each learned to live with the consequences and maintained solidarity to their own parents.
The initials thing... Yes, we carefully avoided any pronounceable set of initials for our own children although it's only just occurred to me that if our daughter had married someone whose surname began with a Y she'd have become DRY. What we hadn't spotted was the potential confusion when, as happened, she started post-grad research.
