According to Find-a-Grave Rebecca Dailey (b. 25 Oct 1793, d. 29 Mar 1866) and John Dailey (b. 11 Sept 1785, d. 6 Feb 1855) are buried in the Cumberland United ME Church Cemetery, 5384 Rt. 49, Melville, Cumberland County, NJ. Cumberland Co. is next to Salem Co. and close to Phiadelphia, so there likely was a name change over the years. There is a contact person you can call at the church, 856-825-6647.
I can't find any record of a Broadwell Church or Cemetery in Salem Co., NJ, but I hope this information helps you.
