Any further info should be added to the original request which is here;
http://www.rootschat.com/forum/index.php?topic=17579.msg63675#msg63675 Please post any updates to that and I will ask a moderator to delete your 'repeats'.
The additional info which you have not posted, yet indicate you should have:
the names and birth years of children
The 1871 address.
Have you any addresses for kids's birth or marriage certificates?
List those with dates.
If the widow is running a school, then does the Leleux surname appear in
any trade/Post Office / Other directories of the period?
www.historicaldirectories.org List any refs with the address.
If the surname is not in the partial name index, then either it's mistranscribed, or in an unindexed piece, in which case the adress is *required*.
