They weren’t twins then………birth year info in OP is incorrect :-( :-( :-(

Hi there, Yes Nick is a cousin, and we are working together to find out more about the Killeens from SandyMount.

Well spotted: The two English Clark Brothers were NOT twins - James Henry Clark born 1893 and William Thomas Clark born 1899 ( Both soldiers deployed during the troubles in Ireland and they then moved to England between 1924 and 1926 - London area we think.

We follow the William Thomas Clark 1899 Line while Nick Follows the James Henry Clark 1893 Line.

Both brothers married two Killeen sisters from Dublin - When stating a minor do we think under 18? we were told the girls were smuggled out in an army convoy.

To find Williams and James Henrys Parents is fantastic.

Why ? This record is officially closed.

Was John Edwards Clark Father - James Henry Clark and Mary Killeen?
John Edward Clark
in the Ireland, Civil Registration Births Index, 1864-1958
Name John Edward Clark
Birth Quarter Jul-Aug-Sep
Birth Date 1928
Birth Place Dublin North, Ireland

We don't know the surname of "Annie" in 1939 . Her surname ,just shown as a ditto symbol
( " ) is the same as that of the person on the line above her, but that record is closed, and therefore we can't see the surname.
But she's not a daughter of James and May.

Records are closed on the 1939 Register if the person is either still living, or was born less than 100 years ago. Or may be dead, but the Register hasn't picked up on it.

Minors in that era were under 21

The legislation to reduce the voting age to 18 came into force in 1969

Can't tell if John Edward's parents were James Henry and May V without seeing the birth cert, but it seems very likely, as he's in their household in 1939.
Relationships are not shown on the 1939 Register.

Your opening post mentioned the name May Violet, so I assume May V is her.

Nora Ryan

This is the child of Daniel and Elizabeth who had died (per 1911 Census in Dublin):

Garrett a more popular name than I imagined - just went through them all until I found one with mmn Plunkett

Name GARRETT COOLING
Date of Birth 17 April 1903
Group Registration ID 4447980
SR District/Reg Area Dublin
Sex see register entry
Mother's Birth Surname PLUNKETT

From original -
The surname does appear to be Cooling - misheard I suspect. But Father is Daniel a Tram Car driver of 10 Church Lane.

Good find, Greyghost!

I thought I'd looked at all the possible mis-spellings, but missed that one!

So maybe Bernard is Benjamin in 1911 Census. Maybe enumerator's mistake.

There's definitely no sign of the birth of a Benjamin with mmn Plunkett, 1903-11 in Dublin.

Thanks AG, but I missed Daniel on same page as William!!

1911 census said 8 born, 7 living. So Benjamin/ Bernard look to be the same person.

Mary - 9..3.1893
John - 22.10. 1894
Elizabeth -15.8.1896 (Lizzie, Lily)
Daniel - 28.12.1898 - born 11.45 pm (see below)
William - 28.1.1899 - transcript has this date but writing out a list shows this to be an impossibility if born 1 month after Daniel Original gives DOB as 28.12.1898 so twin to Daniel
Francis - 31.5.1901
Garrett - 17.4.1903
Bernard - 20.9.1905

Thank you All so very Much

This is amazing and has very much identified the siblings we've been looking for.

Now I need to find any descendants :)

Killeen/Sullivan births in Dublin from 1934 - probably Garrett and Ellen's children:

Elizabeth M Killeen 1935
Donal G Killeen 1939
Garrett J Killeen 1943
Anthony F Killeen 1937


Anthony Francis Killeen is on an Ancestry tree, with no supporting paperwork apart from his birth record.
The tree says he married Eileen Melia (1938-2009), and he died in 2014.
The tree shows two sons and two daughters, with their details kept private.

The tree owner is Deborah Killeen, who appears to be one of the daughters.
She hasn't been active on Ancestry for over a year.

Births Sep 1931 (>99%) - Not sure this child belongs to William & Lillian Clark

I'm wondering if the baby survived

Look for a death

Only two possible younger children with them - though the closed records could be anybody, not necessarily children.

I don't see them in 1921.

If Lilian is Elizabeth (birth posted on page 1), her year of birth is wrong - 1902 instead of c1896-7, as in birth record on page 1, and Lily's age stated in 1911.


You would have to buy Mary's birth cert to see if she's William and Lilian's daughter or not.
I don't see a likely death for her , 1931 - 1939

I see you have Lavinia Clark 1920 on your GR tree, Kelly, born in Dublin.

How do you unclose a record ?
Lavinia was born in Dublin.

William Thomas Clark married Lillian Killeen and had 4 Children
Then William Thomas Clark went off with his niece Anna Elizabeth Violet Clark daughter to his brother James Henry Clark and their child / daughter was Jessica Clark ( My mother in law) As you can imagine massive rift, we are trying to find out the truth through records.
I'm wondering if that is why the records are closed
