Certificate of Freedom to Marry and witness requirements

Hi there,

I require a Certificate of Freedom to Marry as part of marrying a non-EU citizen in their country. The signed application form needs to be witnessed and the foreign affairs department in ireland website lists the following conditions required for the witnesses:

Who can be a witness?

Your witness must:

• Know you personally
• Know a third party personally who can identify you
• Be able to verify your identity through your official documents (e.g. a passport)

Applying in Ireland

Your witness can be:

• A notary public
• A Commissioner for Oaths
• A solicitor

I don't personally know a notary public, a commissioner of oaths, or a solicitor, so how would I go about getting them as a witness? Or is it I just find one and they witness it and the requirement for me knowing them personally is not a real requirement?
