I believe the ladies you reference are both daughters of Thomas and Helen Wray (Stith) Hungerford.I don't have much on Ariana and Helen.I had Ariana W. Hungerford marrying a " Mr. Smith."
I do have some information on some of their sibling's however--and Thomas' pedigree... Their brothers were:
William Henry Hungerford, born 1820 in Westmoreland county, Virginia, died before 1900 in Uniontown, Perry county, Alabama, married Adeline S. (____).
John Henry Hungerford, born about 1838 in Westmoreland county, Virginia.
Maria Louisa Hungerford married Benjamin F. Williamson about 20 Feb 1843.
Their pedigree: Thomas; Lt. Thomas (m. Anne Washington); Thomas; Barton; William Jr.; William.This William died 31 Oct 1662 in Charles county, Maryland.
I would be happy to trade info with you.I'm trying to document all the lines down to the current time--Hungerfords and those that have them in their lines--and I could give you family group sheets with notes and a pedigree chart in return.If you are interested contact me via my e-mail address.Take care.
