 The cathedral chapter tasked Jonas Kazakevičius (Jan Kosakiewicz), auxiliary bishop of Samogitia, to write a biography of Giedraitis, but it was not done.Bishop Motiejus Valančius (1801–1875) ordered a marble tomb of Giedraitis installed in Varniai Cathedral in 1853.On the occasion of the Church Jubilee in 1900, Lithuanian Americans sent a letter to Pope Leo XIII asking to canonize Giedraitis and Andrius Rudamina, the first Lithuanian missionary to China.
