The references are those who can "vouch" for your character and so forth. In the event, you don't know enough, logically I would say just keep attending when you can and getting to know the members. At some point, surely some members will be comfortable enough around you and know you well enough that they themselves would be able to vouch for you. Thus is how many masons who don't know other masons gain membership. Keep attending, do not be discouraged. These men will eventually be called your brothers. Taking time to make friends now will pay off in the long run anyway, just make require some patience. You'll get there!
