Perhaps you should try some spelling variations:
"daniel harris cohen" » "daniel hayes cohen", "daniel garret cohen", "daniel harris corner", "daniel harris ben", "daniel harris case"
"daniel morris cohen" » "daniel torres cohen", "daniel merril cohen", "daniel moores cohen", "daniel morris john", "daniel morris corbyn", "daniel morris noel"
"samuel harris when" » "samuel charles when", "samuel hartlib when", "samuel hayes when", "samuel harris who", "samuel harris ben", "samuel harris w.e"

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (((("daniel harris cohen") OR ("daniel morris cohen"))) OR ("samuel harris when")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"daniel harris cohen\") OR (\"daniel morris cohen\"))) or (\"samuel harris when\"))".
• Removing quotes may allow a broader search: (((( daniel harris cohen ) OR ( daniel morris cohen ))) or ( samuel harris when )).
• Adding a wildcard symbol may retrieve word variants: (((("daniel harris cohen") OR ("daniel morris cohen"))) or ("samuel harris when"))*.
