Alice E. (b. Oct 1854 - 1937) married William W. Potter (b. Dec 1854 - 1928).https://familysearch.org/pal:/MM9.1.1/M545-9BLThe two sisters lived about 18 miles apart just west of Cooperstown, NY. I wasn't able to determine their maiden name.
Ah, here we go, Alice Estella Barton, was born Oct. 25, 1854 in New Lisbon, Otsego Co., NY. Hmm... no sign of a sister. Alice's father, Stanton Barton, died in 1856. Her mother, Cena Louisa, remarried two more times and in the 1900 claims to mothered 5 living children.http://wc.rootsweb.ancestry.com/cgi-bin/igm.cgi?op=GET&db=wrpotter&id=I0301I still have no idea who Clarence was.
Louisa married a Cushman...https://familysearch.org/pal:/MM9.1.1/MC43-WFLThis census record is the missing link - you need to be a member of ancestry.com to see it.http://search.ancestry.com/cgi-bin/sse.dll?rank=1&new=1&MSAV=0&msT=1&gss=angs-g&gsfn=Louisa&gsln=Cushman&mswpn__ftp=Otsego+County%2c+New+York%2c+USA&mswpn=2263&mswpn_PInfo=7-%7c0%7c1652393%7c0%7c2%7c3244%7c35%7c0%7c2263%7c0%7c0%7c&msbdy=1835&uidh=6l5&pcat=ROOT_CATEGORY&h=48171578&db=1860usfedcenancestry&indiv=1...and this one --https://familysearch.org/pal:/MM9.1.1/MZF3-FXVSister Bertha Cashman (Cushman?) is listed with Mother Louisa in the household of William Bennett (who would become Louisa's 3d husband). Alice and Berta were 1/2 sisters.I don't think Clarence was a brother (but am not certain of that!) I'm thinking he was a neighbor or something.
It's amazing you could untangle the relationships so well! Clarence could be an acquaintance or cousin. Someone both sisters knew, but that will probably remain a mystery.
