His father Samuel died before 1864 and William followed him as tenant of the farms numbered 7 & 8 situated in Greaghadossan townland, Killinkere parish, owned by Lord Farnham. In original handwritten copies of the 1856/57 Griffith Valuation of Ireland, presumed to have been drafts subject to correction by the landlord, William was listed as the tenant of the farms, however in the printed published valuations it was was changed to his father who was still alive.
William was the last of eight known Samuel O’Hara and Elizabeth Jordan children to emigrate to New South Wales. His emigration was sponsored by a brother John O’Hara who with his family had emigrated seventeen years earlier. William arrived in Sydney with his wife and five children on the Peterborough on 26th August 1880. He and Isabella were listed in the 1909 Commonwealth Electoral roll, in the Marrickville subdivision of the Lang electorate living at 74, Silver St. with his occupation given as "independant means". His death registration gave his last occupation as "dairyman", which is presumed to have meant dairy farmer, and it stated he was late of 116, Silver St., Marrickville. It is said he farmed at Glen Innes 5 however he was not listed in the Glen Innes subdivision of the New England electorate in the first Commonwealth electoral roll for 1903 through to 1908.

Date advised in letter dated 20 Apr. 1999 from Gwenda Anderson of
Queensland
to the compiler - the data was extracted from copies of the actual
baptism
and marriage records in her possession that were obtained by William
O’Hara
from Ireland before his 1911 death and thus before the actual records
were
destroyed in the 1922 Records Office explosion and fire in Dublin.

or Isabella O'Hara.

Has Isabella's age as given correctly by informant son Samuel as 77 yrs
- i.e. born 1836 - however age of 16 yrs when she married was at least
5 years understated.

Isabella's 1836 Ballyjamesduff baptism stated her mother's name was
Nancy
Lockhead - her 1913 death record stated it as Nancy Lockheed.

Peterborough immigration records listing of ages of the five
children - Eliza 22, Mary 17, Samuel 15, John 11, Isabella 6.
7
William O’Hara's 1911 death certificate stated 4 female children
pre-deceased him. As two of the three daughters who arrived in
1880 were deceased, it is implied two others were born in Ireland
and did not accompany their parents and the others to Australia in
1880 on the Peterborough, either because they had already married
there, died before departure, or for some other reason.
8
The two children birth dates are from LDS Church's British Vitals
CD-ROM - presumably extracted for the CD from the civil registration
records that only commenced in 1864. The CD also listed that a
William O’Hara & "Elizabeth" Watson had a daughter Margaret
Anne born 19 Sep 1871. All three are listed as Bailieborough, which
was the nearest town to Greaghadossan townland, so would have been
the place of the birth registrations. It is possible Margaret Anne's
mother's name was recorded in error as Elizabeth instead of Isabella.
If so Margaret Anne O’Hara would be one of the two unaccounted
for daughters not in the family group when it arrived in Australia
in 1880.

A Young family genealogy compilation
dated 14 Aug 2007 listed "Reginald l. E. Young born 1895 who did
not marry" as first born of seven Isabella Jane O'Hara and James
Percival Young children. However he has been excluded as their
child of from this compilation for the reason that there is no
evidence in the NSW BDM Indexes of a birth registration under either
the O'Hara or Young surname betwen 1894-1896 of a child with the
given name of Reginald and no death of a Reginald I. E. Young
having either parent with those names is indexed from
1895 to the current death index termination year of 1976. Also
sister Lily Fisher's 1993 obituary did not name him with the
other five as a sibling living or deceased - see source citation
10above. Even though purported born 2 years before
the mother married, it would be expected if he had
been Isabella's child, that as was usual practice in such a
circumstance there would have been a birth registration under her
O'Hara surname. It also seems most unlikely she would have had
two children named Reginald unless the first born died before
the second was born - in this case before known child Reginald P.
was born in 1911. If the purported child Reginald I. E. was
alive when Isabella Jane died in 1960 he should have been listed
as such in her death registration. Also if Isabella was the informant
for the birth registration of her 1898 born child Ernest Arthur's that
registration should have her previous issue given as - "1 male".
None of these records have been consulted by this compiler. Pending
some acceptable evidence becoming available, such as for example
a unambiguous birth notation in a family bible, Reginald I.E.
has been excluded. He may well have been an adopted child, a
brother or a nephew of James Percival etc., who lived with the
family but with his actual history unknown of today and just
assumed.
