These are balllots being returned by voters who requested them.  The absentee list should have the voter's complete name and street identifier.  If the officers of election can determine from the information given that the ballot is being received from someone on the absentee list who applied for it, then they should accept that ballot.  If both Robert Smith III and Robert Smith IV live at the same address and only RSIII requested a ballot, then the ballot being returned by Bob Smith can be properly identified as his.  If both voters requested ballots and only one has been returned, then it cannot be identified.

Similarly with street name identifiers, if Robert Smith, whose voting address is 100 Main Street, has requested a ballot, then the ballot being returned by Bob Smith, 100 Main, is identifiable, unless, of course, Robert Smith from 100 Main Road also requested one.

If the voter can be identified as someone on the abdsentee list, the ballot should be accepted.
