Deer Isle history, by Hosmer
Ignatius Haskell, Esq., after the death of his father, did the business here, in trading and building vessels, for several years, and for the times and locality it was quite extensive. He was a moan who had a large share of business capacity, and for a long time was the foremost man in the community, and had great influence, owning a large property, and taking great interest in the affairs of the town and church. He built a meeting house at his own expense, not far from the year 1800, selling the pews to those who were disposed to purchase. He was one of the earliest justices of the peace here, was often one of the selectmen, and was, in 1819, a delegate to Portland with Asa Green, before named, to the convention that framed the state constitution. He retained his faculties in a remarkable degree till the time of his death, 1842, at the age of 91 years
The following note from World Family Tree, Vol. 85, tree 746:
Mark went into business in Castine with his brother-in-law, Jonathan L. Stevens, but afterwards returned to Deer Isle where he conducted a general store for many years in a building owned by him that stood where the Dr. Wasgatt drugstore building was erected and later used by Percival Knowlton as a printing office. Mark was an honest, capable man and much respected. Upon his death, aged 61 years, his property passed to his wife. It consisted of part of the house owned and lived in by his father Ignatius (Esq.), and known as 'The Ark'. They had no children.
