Seeking 1st Class Relic with Papers for an Altar: Help!

I am trying to help acquire for an FSSP apostolate a fourth and final 1st class relic (with papers please note) so that four reliquaries can adorn an altar in reliquaries.

A martyr would be wonderful, but any saint will do.

If any priest or otherwise can be of assistance, please contact me by email: stribe@rogers.com
