I found Leonard's obit., he died 3/5/1992 in Gardner. From the obit, this is what information I have.Emily was born 1/24/1921, died 7/22/2002 in Carver.Her married name was Emily French. I did not look for her marriage.
Josephine his sister, married name Josephine Sapiknowski was living in Plymouth.Could not find anymore information. It is possible she is still alive. Leonard's brother Gordon was listed also as living in Ayer.
I will still look to see if I an get an obit for Gordon, Emily or Josephine.
