A connection at last - very windy day her in south Suffolk ! 22h20 Sunday evening and the winds have died down at last.
The information for Melles/Mells would probably be with the parish records for Wenhaston St Peter's they run from 1687-1900 at the SRO, and should be available to order from the LDS.
I look after all the Local History Recorders in parishes throughout the county (and have info on those parishes which became part of Norfolk in the county boundary changes) and I can assure you there is no Walston in Suffolk.
I dug out my copy of 'Origins of Suffolk Place-names' today and checked with accent pronunciations too in fact, a friend of ours Robert Malster has written about the Suffolk accent and dialect and our daughter who studied English Language at Uni wrote her thesis on same subject).
Bearing in mind that the Suffolk accent would say Wall for Worl I am wondering now about Worlington. When I did have a connection this morning I checked randomly for Flack and there was an amazing amount of folk with this name in the Lakenheath/Mildenhall area in1851.
The only other place I can think of is West Row, which of course is said as one word Westrow - still doesn't make a great deal of sense though.
I also checked through the info I have on my home PC for my website and see that you have registered in the past and I was unable to help further with that to see if any other areas are predominantly 'Flack areas' of the county.
I have been out of action, stuck at home, following surgery and 8 weeks R&R, am nearly six weeks into that - but all being well, once I have finalised our LHRs conference day in October, I will be able to visit the Bury branch of the SRO and maybe able to carry out some look ups for you in possible parishes.
