John Robert Westwell Military

I have switched over from working on my Taylor/Rothwell branches to working on my Westwell branches.

One thing that I was pursuing was the discovery that Robert Westwell, born 1868 was a soldier according to the 1891 census:

So, I took advantage of a free trial from Fold3 to look for British military records for a Robert Westwell. While I didn't come across anything definite that would match the Robert Westwell that I am looking for, I did come across a record for a John Robert Westwell.

While it's not the name that I'm looking for, could it be connected to the same Westwell family? Further inspection of the record indicates that John Robert Westwell lived in Blackburn, Lancashire, like the rest of the Westwell family.

Looking further, I see that John Robert Westwell enlisted in 1858 at age 18, and was listed as being 39 years of age in 1879, both facts suggesting a birth year of 1840.

But a name of John Robert Westwell born in 1840 doesn't match with my Westwell family, because there is is a Robert Westwell born in 1838 and a John Westwell born in 1850, so it does not appear that this individual is connected to my family - at least not unless it is much farther back.
