The Romnichels are a distinct group of Gypsies, with origins in England. Derivations include Rom'nie. Sounds similar to Romany, the term in older literature for Gypsies, or Romani. Or Romney.
They sound alike for good reason. Romana, Romney. Gypsy surnames dating from 1567, see, fair use from the PDF site,
"ROMANA/ROMNEY 1567-1623 (int) Shrophshire, Suffolk) (See Robert Dawson ARITF)", from JJ Gypsy Index PDF.

We have an interest in geneology as it may or may not be evidenced in last names, for recreational thought, and here focus on the last name, Romney. The Gypsy Lore Society addresses the Romnichels or Rom'nie, at ://www.gypsyloresociety.org/cultureintro.html. .
Actual Romneys may well have their own family tradition of origins, but the name Romney - Rom'nie standing alone suggests English Gypsy roots: dealing in draft horses, horses for transporation, horse traders, basket makers and that term included making rustic furniture, and fortune telling.
See this Gypsy Lore Society site for description of this group and many others, along with the trades that the groups specialized in: Scroll down to Romnichel. The information is from a further book's introduction, "Gypsies and Travelers in North America: An Annotated Bibliography," by William G. Lockwood and Sheila Salo, that book linked at ://www.gypsyloresociety.org/books.htm.
Update - here is a young man in Kent, England, who identifies as a "romney gypsey" in a message board entry dated 1/29/06 at ://www.bbc.co.uk/kent/have_your_say/community/romany_voices_archive21.shtml.
Compare the Rom. The Rom were Gypsies not from England, but from Serbia, Russia, and Austria-Hungary says the same Gypsy Lore Society site. Coppersmiths, including "repair and refinement of equipment used in bakeries, laundries, confectionaries...." They also told fortunes. The Kalderash are a Rom subgroup.
The "Black Dutch" group of Gypsies has largely been absorbed into the Romnichels. Same Gypsy Lore Society site, scroll down to "Black Dutch." This group was from Germany, but the term is also used for other non-Gypsy groups apparently. Again, horse traders, basket makers, and many provide to the Mennonite and Amish communities. See Pennsylvania Dutch. Hard to get reliable info on "Black Dutch," says site.
So: the papers already have found an ancestral link between Vice President Cheyney and Senator Barack Obama, ://www.bostonherald.com/news/national/politics/view.bg?articleid=1040896, and this adds a possible Mitt Romney to the ancestral Rom'nies.
In a name. See ://website.lineone.net/~rtfhs/gypsy.html
Other Romani first names: Dangerfield, Cinderella, Britannia, Sabina 9those Sabine women?)
And surnames: Lee (Gypsy Rose Lee?), Ayres, etc. and the site notes that all with those names are not Gypsies, just that Gypsies with those names traveled in England. At Geneology Forum you can join the fray in searching for answers with probably no way of checking what you get. Still, recreational.
