Finding Related Directorships (same human being but different officer_id)

I’d like to understand if the following is possible, because it seems like it isn’t but perhaps I have missed something.

Company XYZ has 3 directors each with their own officer_id.

I want to find all related companies where any of these 3 directors are also directors. I have understood how to do this using the officer_id: that doesn’t present a problem. The problem is searching for related companies where it is the same director BUT with a different officer_id.

For example:

  • John Devanport - officerID = 987654321 - DOB = 12/1978
  • John Mike Devanport - officerID = 123456789 - DOB = 12/1978

A human understands this is (probably) the same person very easily. Is there a way to search using Name + DOB to return a list of officer_id’s?

Many Thanks,
Keith

I would also be highly interested in this kind of information data. In case you are allowed and able to, please forward existing data to me as well. Thanks!
