Seaching for Relatives of Darunee Pomwong

I am trying to locate my mother in laws family, her name is Darunee Pomwong who was born in Udon Thani in 1955. The majority of her relatives 3 brothers and 4 sister lived in Nakhon Phanom. Her brother Boonchai (spelling) was in the Thai Army, Lein (spelling) was a police office, Tain (spelling) owned a store. Darunee's sister Mia (spelling) husband was a school teacher possibly in Wanon Niwat, her sister Waunetta (spelling) was married to a man possibly named Dave David who owned a factory, her sister Sung (spelling) lived in Wanon Niwat farming rice with her husband and Chaing (spelling) was deceased. Moms name was Boonda (spelling) and dads name was Photongma (spelling). I know the spelling of the names are probably incorrect but it was the best we could do since my mother in law has not spelled in Thai in years. Any help would be greatly appreciated.
