My name is also Anne - but there are so many at Rootschat, I was forced to go with something else.  
Well it certainly looks like the "plot"is thickening.   I am so glad to find not one but two of the Upton line.  
England & Wales, FreeBMD Death Index: 1837-1915
Name:    John Upton
Birth:    abt 1793
Death:    Jan- Mar 1868 - Market Bosworth, Leicestershire
John Upton, age 75, Jan-Mar Market Bosworth, Vol 7a - page 50
Do you have the Death Certificate?  If so does it identify his parents?
My Henry Upton was born 13 Jun 1813 in Desford to John & Rebecca Lester Upton; He married Anna Sutton about 1843 & they had a daughter Rebecca born 9 Jun 1844 Market Bosworth & a son John b cir 1846.  In Jun 1847 they moved to Philadelphia, Pennsylvania on the ship, London.  Anna soon died & Henry married again & had a son James Joseph Upton b 1849 in Philadelphia - my great grandfather.  Henry was a Framework Knitter and at times listed as stocking Maker, employed in Philadelphia.  There were other Uptons of Desford who moved to Philadelphia.  
Did you have this marriage? 
1821    Oct 01 -Henry Upton, Framework Knitter -   Charlotte    Hollis spinster    Banns Desford 
Witt: Thomas Upton & Ann Fradshaw. (Must be your lady, she would marry the next year to John Upton.)
I will go back in my Desford pages and see what else I can find for the Mary Dexter/John Upton family.  His tombstone as listed by WGU puts a crimp in who I thought he was.

I have 300+ pages of Desford Parish copied jpgs (you are welcome to any and all) In April I will be in Salt Lake and will copy more.   Do you have access to the Parish records?   
I would like to collect as much as possible before I go - so I would appreciate any ideas either of you have or corrections or "facts".   
Any suggestions of research appreciated.
