To summarise:
James CARR
marriage cert - suggests birth c1875, father James CARR, labourer, deceased.
army record - names mother as Rose McGRADY(?) in Hebburn. Brother John CARR
army record - James aged 26yr1mo in July 1908. Religion: RC
army record - James CARR discharged June 1915
army record - home address 93 William Street, Hebburn
Is this the same person as Sgt James Bernard CARR, of the DLI and Labour Corps killed 2 Jan 1918? Son of Mrs KENNEDY of Hewittson Terrace, High Felling (James was at Field Street, Felling when he married in 1902) our James was invalided out unfit, bad conduct, so is it likely he rejoined and became a sergeant?
The likeliest scenario is:
James' mother was Rose
James' father probably James CARR
James was born c1875
as James jnr had a brother surnamed CARR, Rosie may have been Mrs CARR
widow Rose married Mr McGRADY(?)
The only CARR/McCREADY (and variants) marriage I found in Durham is:
(FreeBMD) Rosanna CARR Dec qtr 1874 Sunderland vol10a p902 - on the same page is Edward McCREADY
The 1881 census has: RG11 4993/18 p30 - Brougham Street Sunderland (all surnamed McCREADY) - Edward 26, Rosana 27, children John E 4, Francis 3, James 1 & Elizabeth 0.
The 1891 census has: RG12 4138/96 p13 - Ward Street Sunderland (all surnamed McCREADY) - Edward 36, Rosana 37, children John E 14, Frank 13, James C 11, William M 8, Nora R 6, Mary A 4 & Ernest P 1.
This is most probably a red herring as it does not fit a birth date for John, but it will save other Rootschatters chasing it!
I'm off to hunt censuses for John CARR with mother Rose to see if anything turns up.
