"Index for the Encyclopedia of PA Biography, Book 2, Index, Volumes XXI-XXXII, Surnames C-D, Page 52.
The explanation of from where the data came is below.
Hoping this may help.

The Encyclopedia of Pennsylvania Biography is a 32-volume collective biography that was published in irregular intervals from 1914 to 1967 by the Lewis Publishing Company. Virtually all of the biographies identify the person's date of birth, parents, spouse and children, and some provide extensive genealogical notes. Both published cumulative name indexes are published here in one. In both cases the indexes furnish the name, volume, and page number of every subject of a biography in the Encyclopedia. In this way, the Index constitutes a crucial new finding aid for persons with Pennsylvania ancestry. It will be of great use to the many institutions that already own the Encyclopedia of Pennsylvania Biography. Similarly, researchers who buy the Index but have no access to the Encyclopedia can write to the
Free Library of Philadelphia,
1901 Vine Street,
Attn: Social Science and History Department,
Philadelphia, PA 19103
for photocopies of short biographical entries whose subjects they uncover in a check of the Index.
