user16806: I need a list of all the people mentioned in the Pali canon who were in the story of the historic Gautama the Buddha. For e.g. Angulimal, Ananda etc. I did a google search for the same but did not find the answer. Also, if you can provide sutta reference for their mention that will be great.

user471: Please try AccessToInsight (ATI)'s Index of Proper Names.
On this page, please search for the following phrases:

"Buddha's"
"of the Buddha"

You will find phrases like "Buddha's father", "Buddha's cousin", "son of the Buddha", "Buddha's first meditation teacher", "half-brother of the Buddha", "Buddha's chief personal attendant" etc.
The ATI page will provide sutta references, if available.
For a description, please next refer to Palikanon's Buddhist Dictionary of Pali Proper Names.
For example, on the ATI page, you can find:

Suddhodana (Buddha's father): Sn 3.11

Then on Palikanon:
