An e-mail from a British ex-Pat:

I [like] the idea of highlighting July 4th martyrs for freedom, but
I would question your choice of a 16th Century Catholic in England as
an example (perhaps the Child-Martyrs, the children of Tsar Nicholas โ€“
Olga, Tatiana, Maria and Anastasia โ€“ who were murder in a in cellar in
Ekaterinburg on the night of July 4, 1918). The Catholics in England at that time were not fighting for religious
freedom, in fact under the reign of Queen Mary I they had killed an
estimated 284 Protestants in the Marian Persecutions (1555-1559),
burning them alive on bonfiresโ€ฆ

Update Fourth or Not: Another e-mail:

The Romanovs were killed on July 17. They only died on July 4 if you are using the old Julian calendar.

P.S. While I understand the Abbot pushback but stand by the example. Here I stand โ€ฆ
