Hi Penny,
Before I started sending you this I thought I had better check with you as I found this in the Monumental Insciptions taken from Holy Trinity, Castle Street Burial Ground as was. Most of stones eroded but Parish Records for Burials give an idea when died. Hopefully your Rebecca date different.
So everything below is as transcribed.
Sacred to the memory of MARY THOMPSON Who died (?) 18(5)(1,4)/ AGED (?) YRS. also REBECCA HOBSON (??) 18(42?)/ aged (?) years.
Parish Record 25 Jun 1842 Catherine Hobson, Myton, 75yrs,
PR 10 Jul 1807, Mary Thompson, Widow,
PR, 03 Sept 1807 Mary daur of Jno Thompson, Myton,
PR, 29 Mar 1857 Mary Thompson, Myton, 77yrs
PR, 22 Nov 1857, Mary daur of Edward Thompson, Myton, 12mths,

All buried in the same grave, I wish you all the best with that above.
Also as you will see Rebecca Hobson must have been written down as Catherine on the Parish Record entry.
I think Israel Hobson may have been born in Beverley, I have a Hobson family with some parish record entries and there was an Israel Hobson down on these entries, will check for you if you want.
All the very best with the above,
