Andrew Ferdinand Gregerson

He sailed to America in 1862 on the ship Athenia.  No family members accompanied him.  According to a secondary source, his mother sent him to Utah with a family by the name of "Madsen."  Their names appear on the ship manifest and on the Joseph Horne pioneer company roster, so it is likely that Andrew came on to Utah with them, as he was only 13 years old.  

The years of his birth and death are confirmed by his obituary and the inscription on his gravestone.
