Perhaps you should try some spelling variations:
"samuel harris cohen" » "samuel charles cohen", "samuel hartlib cohen", "samuel hayes cohen", "samuel morris cohen", "samuel harris when", "samuel harris corner"
"daniel garber cohen" » "daniel gabriel cohen", "daniel baker cohen", "daniel werner cohen"
"daniel albert cohen" » "daniel alberto cohen", "danial albert cohen", "daniel gilbert cohen", "daniel robert cohen", "daniel albert count"

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: (("samuel harris cohen") OR ((("daniel garber cohen") OR ("daniel albert cohen")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"samuel harris cohen\") or (((\"daniel garber cohen\") OR (\"daniel albert cohen\"))))".
• Removing quotes may allow a broader search: (( samuel harris cohen ) or ((( daniel garber cohen ) OR ( daniel albert cohen )))).
• Adding a wildcard symbol may retrieve word variants: (("samuel harris cohen") or ((("daniel garber cohen") OR ("daniel albert cohen"))))*.
