Does anyone have information on Slovak Lutheran church in Delray?

Hi, I am looking for any information on Slovak Lutheran congregation in Delray between the years 1910 and 1920. While the congregation still exists and moved to Taylor some years ago ( http://www.ourredeemertaylor.com/history.html ) I would like to find information on members of the congregation at that time which would not be kept by the church. I know that the congregation used to take photographs of certain events and it would be great to see these.
Also, I have attached a picture of a badge or some kind of insignia member used to wear on their coats and I would like to know more about it.
The pastor at that time was Rev. Andrew Daniel and again, any information about him or his family would be appreciated.
