“A nation can only be free, happy, and great in proportion to the virtue
and intelligence of the people.”

Stephen F. Austin

Below, at the bottom of this page, you will find the applications for Junior and Adult Membership.   Additionally there is an application for the Grave Medallion that is available to Certified Members by application only.

There is a non-refundable application fee of $75 to apply.  This $75 fee is due with the submission of your paperwork to the registrar. This payment will be converted to your first year's membership dues upon acceptance into membership by the registrar.  Dues will then be $50 annually, to remain a Member in Good Standing.   Your annual membership dues allows our organization to operate and promote the History of the Old Three Hundred and their place in Texas History.   

All membership inquiries should be addressed to Charleen "Charlie" Mullenweg, Registrar, at  All applications (on legal sized paper) and supporting proofs (on letter or legal sized paper) should be mailed to her at:

Charlie Mullenweg, 406 Oat Meadow Drive, Pflugerville, TX 78660 

Please do NOT mail applications or proofs to the address in San Felipe (below) as we cannot receive mail there.

The applications below are fillable pdfs. (Be sure to save the pdf after filling so it can be emailed as an attachment.)
