THE FIRST HALL AT TYABB.
COPY LINKS INTO YOUR SEARCH BAR TO ACCESS ARTICLES.
His name was James and his wife was Elizabeth nee Dunlop. Their son, James Adam, was born at Tyabb in 1866 (reg. no.17967/1866.)
An earlier son, James*, was born in about 1863 and having died, aged 2 (presuming that meant years) on 19-9-1865, was probably one of the first buried at the historic Tyabb cemetery just north of Hastings.

Poor little James had been born at Westernport, probably Tyabb, in 1863.

James was almost certainly the Mr J. Hall of Westernport who drew these two terrific views shown in an 1866 article.

If J.Hall, later the caretaker of the Tyabb cemetery, was James, his caretaking would have been a labour of love! His second son, born in 1866, died at Tyabb in 1886 at the age of 20 and was probably also buried in that cemetery.

It was the interest of Mr J.Hall of Hastings in social science chiefly concerning trees (potash from mangroves* and cultivation of lemon and orange trees**) which made me try a Tyabb search.

Found with a "Tecoma" Hastings search.
HASTINGS
It is with regret that we have to announce the death of one of the oldest residents of Hastings, in the person of Mrs Hall, who passed away at her late residence, "Tecoma," after a very short illness, at the advanced age of 85. Mrs Hall was suffering from bronchial pneumonia and heart failure, which only caused the deceased lady to be confined to her bed since Thursday last. Much sympathy is felt for Mrs Watt, of Gowrie, daughter of the deceased lady.
(P.2, Mornington Standard, Frankston, 1-8-1914.)

WATT—HALL.—On the 3rd August, 1910, at Melbourne, by the Rev. T. Edwards, Presbyterian minister, James M. Watt, of Hastings, to Amy, only daughter of the late James Hall and Mrs. Hall of "Tecoma", Hastings. (P.13, Argus, 8-10-1910.)

No wonder I couldn't find Amy's birth record or marriage record. I was starting to think she'd been adopted. I looked for James Watts' marriage record.

WATT Amelia Death
mother: Elizabeth nee DUNLOP father: HALL James
places of birth and death: QUEENSFERRY???, HASTINGS
80, 1941, 21559/1941

The place of birth given in a death record can't be trusted! It is possible that Elizabeth gave birth near Queen St in Melbourne just before her master mariner husband set sail and he registered the birth at Mornington. I wonder if James or Elizabeth was born at Queensferry and the informant misunderstood the registar's question.

James Morice Watt provides yet another example of the many connections between the histories of the area near Tullamarine and the Mornington Peninsula. He was the son of John Watt, one of the ealiest settlers (grantee of Oakfield) at Somerton whose son John Oliver rang the bell at the historic Scots Church at Campbellfield for decades from 1875 to 1922.

After his first wife died in 1854 at 'Oakfield',[3] in 1857 John returned to Scotland with his children on 'Roxburgh Castle'. His eldest daughter, Anne, died at the age of 17 years on this voyage. [4]
John married again to Ann Morice on 3 June 1859 in Old Machar Aberdeen Scotland.https://www.wikitree.com/wiki/Watt-1678

James Hall had married Elizabeth Dunlop in 1860 (register number 2079/1860.)
