mmm…. this looks to be the death entry for James & Harriet’s son Aubrey
I wonder what the initial ‘R’ stands for could it possibly be Randall
?
Aubery J R Perrin b1872 died age 80
Jun 1952 Chichester Sussex vol 5H page 443
Hooray I think I have got the answer their surname was
RANDAL
As to why the name change that I can't answer

James & Harriet’s dau Margaret Ellen birth entry Henley 1874 has surname
Perrin that possibly narrows the name change between 1872 - 1874 (Aubery John
Randal b1871 Henley - Margaret Ellen
Perrin b1874 Henley)

James marriage certificate hopefully will give you his father or perhaps mother's name and hopefully you can find the correct James on earlier censuses
I haven't found James Toovey Randell's birth entry but who knows what name was used

There are these James Randall 1846 Berkhamstead,1846 Bicester, James Randall 1844 Henley &
James Randall 1852 Wycombe
At least you know have James' marriage & his son Aubrey's birth entries - if you do purchase them please come back and let us know what they say
