I wouldn't worry about this - what people used to refer to as VD became STD and is now most commonly abbreviated STI, so your son's peers are unlikely to make the connection (and anyone old enough to think of the old acronym would know better, one hopes, than to descend to juvenile teasing). The names do sound good together, very classic but also rather dashing, I find. If you were looking for a substition, I rather like the suggestion of Victor Adrian though.

Congratulations and enjoy your little one!

danasurfside-I like your suggestions for substitution. However, since the title of this part of the forums is "Name Announcements" I think that this is a done deal. I agree with kalmia that it is a rarely used connection anymore and hopefully won't cause any problems for little Victor.
