Can anyone identify this family, with Kell(e)y connections, buried in Mentor, Ohio (Lake County)? The graves are all in a row, so I assume there is a relationship among the individuals. Were the Kellys siblings?

Thomas Kelly b ~ 1803.

Margaret Kelly b ~ 1804--married William Radcliff

Ann Kelly b ~ 1812--married William Caley

Caley, Ann; Caley, Infant

(I believe Ann Caley is the wife of William Caley; married at Hambden, Geauga County, April 3, 1830.

Listed in the 1830 Painesville Village census: William Caley 1 male 20-30; 1 female 20-30.

In 1840 Mentor census, William is listed with one daughter: William Caley 1 male 30-40; 1 female 5-10.

William Caley has not been located in the 1850 census in Ohio, and is not listed in the Lake County burials. (Perhaps he moved away?)
