They often listed pall bearers, ect, again possible relatives. Marrige info is best obtained locally, at the town clerk site. Churches will usually search for a small donation. Also might query the local historical society about cemetery plots in the Russell name, as family is often buried togeather, or at least in the same cemetery.
