I knew:
S. , don t know method, age 21
G., went in front of a train, age 32
J. , don t know method, age 29
E. , don t know method, age 34
C., don t know method, age 19
C., did not know her personally only her sister, hanged herself, age 20
N., my cousin, don t know method, I believe he might have hanged himself, age 49
D. SN, age 50

The list might not be complete. That's the ones that come to my mind spontaneously.
I did not see it coming with anyone.
