Newspapers
There are two books by Mark H Welchley, that when used together, provide abstracts from the Beaver County Argus newspaper from 1830 - 1858. Argus Genealogical Gleanings covers 1830-1838 (FHL US/CAN Book 974.892 V28w). Beaver County, Pennsylvania Marriages from Beaver County Newspapers (FHL US/CAN Book 974.892 V2w) covers 1830-1878.

Vital Records
For death records between 1852-1854, 1893-1906 a great resource is Helen G Clear's book Registration of Deaths, Beaver County, Pennsylvania (New Brighton, Pennsylvania : H. G. Clear, c 1984) [FHL US/CAN Book 974.892 V2c].

Beaver County has two volumes of Death Registers that together cover 1893 -1906. The FHL has these on microfilm.
