I am neither an Agar nor Somers, but I thought this marriage announcement would be helpful to the people who are either directly descended or otherwise related to this couple.(Please note: "Spring Garden" is now very much a part of the city of Philadelphia.The city was not consolidated until 1854.)
Public Ledger - Philadelphia; Wednesday, March 31, 1841, Page 2:
"On the 28th inst., by the Rev. Mr. Gary, Mr. ISAAC AGAR, of this city, to Miss AMELIA J. SOMERS, of Spring Garden."
