Hi dathai, hallmark and sinann,
I just make a point about all of this information to reconstruct the family:
.. Father Daniel Harte
.. Mother: Ellen Boylan born ca 1855
Together married October 26, 1868 Birr, Co. Kings - Ireland
.
Childrens:
.. Mary : born January 13, 1870
.. John : born March 23, 1872
.. Richard : born May 23, 1874
.. Daniel : born August 5, 1876
.. Agnes : born ca 1890
.. Ellen : date of birth unknown
.
My observations.
Joseph David on his military record says only his brother John and his 2 sisters Ellen and Agnes.
But curiously it does not specify the names of all other children born before him : Mary, Richard,,
About the child named Daniel: From the documents that I have (military record and certificates GRO) the married person Daniel (02/05/1906 Portsmouth) with Constance Alice Montifield and then (07/24/1919 Salford ) with Elsie Cain was born
around 1885 (between 1883 and 1886)
So it can not be the same Daniel who was born above him precisely in
1876.
Or may be two Daniel in this familly : One Daniel and one Daniel Joseph ??
Furthermore the military booklet Daniel Joseph Harte
18 years and 5 months and not
28 years.
.
Also I think there is a problem about the search on the name of Harte and that, unless I am mistaken, we are not talking of the same family.
It is likely that Daniel, Daniel's father Joseph Harte was married to someone other than Ellen Doylan. But who

What do you think ?
