Although arguably there is no connection between the meaning of a surname and a coat of arms, the origins as known seem to us unlikely given that a coat of arms of great prominence was granted to the family of Hurtado de Mendoza in circa 1600.
Freezing meat keeps bacteria in a dormant stage. However, once thawed, these bacteria can become active again. Never thaw meat on the counter or let it sit out of the refrigerator for more than two hours. In the summer, reduce this time to 1 hour.
Unless your fridge is above 40 F (4 C), it won't go bad. I've had large frozen turkeys take 4 days to thaw before. Just use it once it is fully thawed, don't let it sit around thawed for several more days. There's no food that I'm aware of that goes bad in the time it takes to thaw it. The stilltasty link below shows 3-5 days for refrigerated meat, and 4-6 months for frozen. Transitioning from frozen to thawed though, I generally count on defrost time + 2-3 days. If you want to thaw it faster you can always use the cold water method. Simply place it in a sink full of cold water (submerged) and change the water every 30 minutes. The rule of thumb for turkey is 30 minutes of thaw time per pound. I imagine pork shoulder would be similar, maybe a little longer? Additional Info:
