It looks like those two Davorens are actually the young daughters of my GGG-Grandparents:
Patrick J. DAVOREN, (1833-1920) & Catherine (FLANNIGAN)DAVOREN, (c1830-1905). Patrick & Catherine were both from County Clare. They met in Milford, MA back in the late 1840s. They married and relocated to Chicago after the Civil War (circa 1865).
Children of Patrick & Catherine:
MARY DAVOREN (CONSIDINE), (1856-1921); ELIZABETH DAVOREN (SHANNON), (1854-1884); CORDILLIA (DELIA) DAVOREN, (1858-1879); CATHERINE DAVOREN, (1860-1861); CATHERINE DAVOREN, (1865-1873); JOHN DAVOREN, (1868-1894);
Patrick, Catherine and all of their other children are buried together in the same plot, (Lot 24, Section K, Block 7) at Calvary in Evanston, IL.
I've always wondered where the other two daughters were buried. My GGG-Grandfather's Civil War records listed the birth & death dates of these two children. My burial dates match up exactly with your dates. But the Cook County Clerk's Office couldn't locate Death Certificates for either of these children.
I have quite a bit of info on my Davoren lines. But none of your ancestors names match up with mine.
Here's something more to add to the puzzle:
I have a copy of the plot records from Calvary. Patrick purchased his plot on December 16, 1879. I find it odd that Delia was buried on December 15, 1879 and that her sister was moved (from somewhere) on the same day. Why would they be buried with your family when their father bought a large family plot the day before?
I should send a letter to Calvary asking them to list where Catherine was originally buried and to give details regarding the removal of Catherine to your families plot.
The only other explanation is that it's one of those cases where the cemetery moves people because of space issues.
Let me know if you have any thoughts on this before I write to Calvary.
