I have Penfolds in my line from Sussex .Have sent a PM to Sue & will continue this way if I can help.A few years ago I made contact with an American family who are distant cousins,proven,of myself.Like many who find they have roots in a different country,they had their tree examined by a professional Sussex based researcher &,so generously, sent me a full copy which is concerned with East & West Wittering where our family originated.This even includes Banns,Baptisms,Burials & Weddings going back to the mid 1660`s & a full appraisal of our family from 1705.I must agree that these Sussex Penfolds were not Romany but farmers,Sussex born & bred.Many in the 1800`s relocated due to the upheaval in agriculture at that time.On the other hand,in my maternal line they WERE Romany,only 3 generations back,again proven by a family contact who still retains the links.Yet,although this line is again from the southern counties of England,I cannot find the surnames mentioned & they did very much intermarry,appearing as Romany families.Each of these sources I think are reliable & by myself could not have gained so much info. unless it came,as it were "straight from the horses mouth."Hope this is helpful.
