last known were abouts of Jashbhai Patel father of Urmilaben(shashiben)

He was known to co habit or had a second family in Rajustha? This came about following working for Indian Army? Nothing else was known, as he had left my mother to her uncle's place for may years and return for few days in 1963 when only once my mother introduced me to him at a frail state in vadodra Harni at harma firworks already a declined factory runby his cousine, and sons. They knew bit more about these as I was too young to know much. Perhaps some one can through some light on this? or let me know what actually happen his eary or late life!
