Jason + wife Anne nee Ellis are both buried in Douglas Borough Cemetery - she buried 27 Jul 1927 age 76, he aged 87 on 24 Feb 1931.
They arrived in Douglas in late 1870's (1st child Thomas born 1 Mar 1877) initially at the 51 Derby Sq with a lodging house named Chatsworth House but sometime in early 1890s moved a short distance to 116 Buck's Rd still keeping the name - in 1904 they had 13 bedrooms + 3 sitting rooms from 4/6 to 5/6 a day - noted that "Trams pass the door" - this was the cable car that ran up the hill and along Buck's Rd.
They had a number of children after Thomas - Percy 1878, Elizabeth 1880 (buried as Lily age 3mnths), Arthur, Albert (buried 1884), Florence buried 1885, Beatric, Frederick and Bertie (your Hubert? ) in 1891 - all the noted children buried in Braddan New.
Bertie is buried Douglas Borough Cem in 1978 age 87 with presumably his wife Janet a year later in 1979 aged 84.
