Hi, sure glad to see some researching this family,I cannot find the marriage record although some one did in 1975, may have been a bible record that we do not have at Licking County Genealogical Society,I have a lot of information on Caroline's family the Hull's. but little information on Caroline other that she was bornca 1829-30 in Virginia to William Hull and Sarah Martin. If you are interested in any of that information I will be glad to share it with you. Caroline is mentioned in her father's will as daughter Caroline with of William Milstead ofRandolph County Indiana. I will Look forward to hearing from you and do hope you will share information on Caroline and her family. you can contact me at firstname.lastname@example.org
Most of our marriage records were destroyed in the 1875 courthouse fire. however many refiled the information and we do have a lot from that transcribed in our library. The Hull family came to Ohio from VIrginia and resided in Fallsbury Township licking county Ohio and it is possible they could have been married in Muskingum County which is close to Licking east.
