Tracing my paternal greatgrand dad's family.

My paternal greatgrand dad was Edward Wholly. He was married to my greatgrand mother around 1872/3 while he was in Pakistan (then undivided India under British rule). He was Station Manager in Jhimpir, Pakistan. There are his death records in the Archives (UK). His birth is given as 1836 and death as 1874. I need some more details, like his originality and other family members.
