Juan Huldrich was buried in Málaga on 27 October 1836. Aged 25, unmarried, he was stated to be a native of Boston, and described as 'Anglo Americano', so presumably the city in question is that in Massachusetts, not Lincolnshire. He was said to have been a sailor on the frigate 'General' and to have died of a bilious attack. Huldrich seems to be an infrequent surname so I wonder if this was actually a John Hildreth?
