Ah, I may have misinterpreted the 'Fynney' wikitree list. I thought the search at the top was within the Fynney list but it must be for the whole wikitree site. Apologies.
However, the arms of Hough of Leighton fit your description and Leighton is only 18 miles from Leek near where the Fynneys were based, so a marriage is possible !
I wonder if the "or three torteau gules" in your no 5 are not Bolougne but are Courtenay (the Earls of Devon family) ? Like you, I am unable to identify the other arms which seems to be "or, a pennon gules"., not a common charge, indeed I can't find an example at present.
As a matter of interest, what is the date of the book you are quoting from ?

PS whilst writing this, Sharon's post has come through. I'll be interested to see what she has for us
