It's interesting that Saroo remembered the word "Ganestalay" but never thought that it might be "Ganesh talay". There are probably hundreds (literally) of tiny villages named "Ganesh" or "Ganesha" in India. One example is the ashram of Gurumayi Chidvilasananda, named Gurudev Siddha Peeth, located near the tiny village of Ganeshpuri, seventy miles northeast of Mumbai.
Ganesh, or Ganesha is the name of the son of Shiva and Parvati. He is traditionally pictured as a boy with an elephant's head. The story is that Shiva impregnated Parvati but was away from home when the boy was born. When Shiva finally showed up Ganesha, protecting Parvati, would not let him in the house. Angered, Shiva took Ganesha's head off with his sword, upon which Parvati told him that was his son, and what had he done? Shiva immediately began looking for a head to put on the boy's body and searched far and wide for a sinner he could kill, until he found a baby elephant who was sleeping with his head facing north. He killed the baby elephant, brought his head home and placed it on the body of his son Ganesha. True story. Wikipedia
