Unfortunately Robin, that doesn't tie in very well at all...
If you're descended from the Platten-Hunn marriage then your not my line - you belong to the aforementioned Norwich/Fleggburgh (Burgh St. Margaret) Hunns. But it's understandable where you got lost, there are many similar names between the two branches and having two James' born in 1838/9 doesn't help matters.
Your line, as I believe it, goes as such:
Ethel (1905) - James (1882, Hoveton St. Peter; m. Emma Jane WATTS) - James (1838, Fleggburgh - 1838, Rollesby; m. Sarah PLATTEN) - John (1811, Fleggburgh - 1894, Fleggburgh; m. Sarah FROSDICK) - Henry (1765, Fleggburgh - 1816, Fleggburgh; m. Lydia KITTLE) - John (c.1734 - 1774, Fleggburgh; m. Mary CHURCH) - John (1704, Acle - 1763, Fleggburgh; Jane HOLSWORTH) - John (1671, Acle - 1721, Acle; Frances READ) - Edward (1634, Norwich - 1708, Acle; m. Sarah ...) - Robert (c. 1609, Norwich; m. Margaret GOULDMAN [dau of Peter Gouldman & Margaret Austen])
As you can see, I have accumulated (with help!) a fair amount of info on this branch also - and it goes back further than my own, so that's a bonus

Any queries just ask.
As for me, I'm off to bed - cos it's 10 to 1 a.m. here in rural Victoria
Night!

P.S. Where did you find the marriage for Robert to Mary Ann Sieg? I was referring to the 1740 marriage of Robert Hunn to Mary Turner in Rollesby.
