Hi
James White Restorick died at 6:30AM on 13th Dec 1862 at 15, George St., St. Helier. He was 24 years old, died from typhus and John Restorick was present at the death.
Source: St. Helier deaths, Dec 1861 to May 1863, volume 15. page 69.
I then looked at the index for burials at Mont a L'Abbe cemetery.
Entry 365 shows "Mr Restorick buried on Thursday, Jan 1875 (no day), in the half burial place, north part of south grave. Minister Rev. Bibby, Funeral Director, Mr Picot". The plot is block F, plot 176, grave N2.
Entry 530 shows "Mrs Restouck on 16th Jan 1877. Funeral Director Mr S". The plot is again, block F, plot 176, grave N2.
Entry 719 shows "16th Dec 1862 - Mr James Restorick to there bury his son - half burial place north". The plot is block F, plot 176, grave N2.
I have copied the plot details and comments as is. Entry 719 is a little difficult to understand but is obviously the burial of James.
