Iroquois female name

[CAROLAN@IDS.NET]

HELP!  I have need to pronounce the Iroqoius name, Jigonsaseh, correctly
at a memorial service tomorrow (Jan.21st).  Assuming that I could find it
within New England's academic libraries I did not query this list.
Unhappily, I have not been able to locate even an extrapolation of it.
If anyone knows, even remotely, how this name should be said *please*
email ASAP.  I will check my mail for the last time at 10:30 AM on the
21st.  Thanks in advance for your help.
