James Biggs would have performed basic military duties and taken part in the building of the capital Stanley.
He died in 1853 having been "accidentally shot", according to records.
"We're a very ordinary family but we have had some fairly interesting times," says Leona.
James did not live to see the birth of his grandson George in 1854. George is picture here (middle, back row) at his wedding to Hororia Shehan on 5 November 1889.
