Perhaps you should try some spelling variations:
seyden » leyden, heyden, beyden
seyedian » seyedin, meredian, lebedian, seedian, sewedian, sayedian, seydian, seyedalian
seyed » seed, sewed, sayed
seyedi » seedi, sewedi, sayedi, seydi, seyedali

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: (( ((seyden OR seydel) OR seyedian) OR seyed ) OR seyedi ).
• Adding a wildcard symbol may retrieve word variants: (( ((seyden or seydel) or seyedian) or seyed ) or seyedi )*.
