On the marriage register for Edward James and Alice are witnesses so I was thinking along the same lines for Edward.
Some examples of Forresters with Moorland connections-
The wills, available on Find My Past, along with family names particularly Gervis lead me to think the Forresters are historically from the Staffs Moorlands area . The will of Gervis Forrester 1745 mentions "lands hereditaments and properties in the parish of Kingsley" . This 1745 will names his wife as Ellen and children Ellen Stockley (married to Moses Stockley 1734),Mary Smith ,John and Gervis. At the time of death he is living at Stoke Hall. Interestingly there are possible corresponding baptisms at Cheddleton for the children of Gervis and Ellen Foster. I may be wrong but these fit well-
"Jhn" 1712 at Leek, then Cheddleton Ellin 1715,Mary 1717,Gervase 1719, James born 1721 and buried 1722. I think this has to be the same family.
Jarvis Foster marriage to Ellin Bagnall 1711 Kingsley.
John Forresters will of 1747 with wife Ann and sons John and Jervis mentions Freehold Estate in the parish of Kingsley and Cunshall? Cheddleton, possibly Consall?
Like Tom I descend from Emmanuel and his son Emmanuel. DNA matches on Ancestry have shown up a lot of matches back to John at Launders Bank. A general DNA search further back for Forresters in Staffordshire gives matches particularly for Kingsley Oakamoor and Alton but this is only a possibility.
As more DNA matches come along I feel pretty certain this is going to show Forresters historically living in the Staffs Moorlands but open minded to any new evidence.
