I'm still digging my way through the family. Sylvanus Jennison is Dolly's brother. Sylvanus Simmons is her son. I found the obits for Rufus Jenison [brother] & his wife. A bunch of the family was buried, then reinterred at Crown Hill Cemetery in Indy. Two plots were purchased: Sec 20, Lot 27 - Rufus' family [13 burials]; Sec 3, Lot 5 - John's family [prob. Rufus' son.] I'll need to check records for death dates.

Have you looked for Jenison, Jemison, Jamison, stuff like that? If you go to SLC, take a look at the Jennison Family History book. I only copied what I thought were pertinent pages. Should have copied those for Dolly's siblings!
