Isaac Yeo and Mary Hammett

Isaac Yeo (1763–1829) was baptised at Okehampton. He appears to have been a grandson of Isaac Yeo and Christian Weeks of North Tawton, but his line of descent has not been fully researched.

Isaac first married Elizabeth Avery; there were no children from this marriage. He then married Mary Hammett at Inwardleigh in 1785 and baptised nine children there:
– Thomas Yeo (baptised 1792)
– Mary Yeo (baptised 1794)
– Isaac Yeo (see below)
– Joanna Yeo (baptised 1798)
– John Yeo (1803–1874, married Jane Woolland, seven children)
– Margaret Yeo (baptised 1805)
– William Yeo (see William Yeo and Mary Ann Spears)
– Richard Yeo (see Richard Yeo and Loveday Turner)
– Elizabeth (baptised 1815, moved to Somerset and married Thomas Hayward, no recorded children).

Issac Yeo (1795–1891, son of Isaac Yeo and Mary Hammett) married Elizabeth Frost at Okehampton in 1826. They had seven children in Devon:
– Thomas Yeo (1827–1876, married Sabina Jane Henwood, four children)
– Isaac Yeo (born 1829, appears to have died as a child)
– Mary Yeo (1830–1877, married Edmund Dyer)
– John Yeo (see below)
– William Yeo (1836–1861, married Mary Ann Bennett, six children)
– George Yeo (1839–1844)
– Elizabeth Yeo (1842–1891, married George McKay)
Isaac and Elizabeth emigrated with their surviving five children to Australia on the SS Theresa in 1847. They had two further daughters:
– Theresa Yeo (1847–1919, who appears to have been named after the ship and was born on board soon after departure; she married William Harold Crocker)
– Jane Yeo (1850–1852).

John Yeo (1834–1901, son of Isaac Yeo and Elizabeth Frost) [note 1] emigrated to Australia with his parents and married three times. From his first marriage, to Olinda Germein in Adelaide in 1859, there were two children:
– Alice Amanda Germein Yeo (1859–1880, did not marry)
– John Orlando Yeo (born 1861, died as an infant),
from his second marriage, to Mary Jane Walters in Adelaide in 1866, there were seven:
– John Yeo (1867–1937)
– Florence Jane Yeo (1869–1895, did not marry)
– Marian Yeo (1872–1959, did not marry)
– Albert Roy Yeo (1875–1897)
– Ada Jane Yeo (1878–1949, married Rupert Pedler)
– Ernest Isaac Yeo (1878–1919, twin brother of Ada Jane, married Florence Wall, two daughters)
– Alice Mary Yeo (1880–1959, married Victor Pedler)
and from his third marriage, to Emma Kate Norris née Germein in 1883, there were no children.

1. Obituary from the Adelaide Register for 27 April 1901: ‘The late Captain John Yeo, who died at his residence Semaphore, on Thursday, was a colonist of 54 years, having arrived in South Australia on the 3rd of May, 1847 in the ship Theresa when 13 years of age. With his parents he settled on Torrens Island, and shortly afterwards went to sea with the late Captain John Germein in the schooner Agenona. Subsequently he purchased the fore-and-after schooner Omea, which traded on the coast for several years and later he secured the schooner Eclipse from Victora, and engaged in the coastal trade, principally to Wallaroo. Captain Yeo then commanded the steamer Kangaroo, well known as a coaster; and in the sixties he relinquished the sea and took charge of the Port Admiral Hotel for about eight years, afterwards retired from active business. At the time of his death, however, he was interested in several vessels trading on the coast, and was a director of the Coast Steamship Company. Captain Yeo was for some years a councillor in the Semaphore Corporation. He has left a widow, three daughters, and two sons, Messrs John and Ernest Yeo.’
