You're welcome. Quick reply there,...I forgot to mention this...
This might possibly be of some use to you...
http://wiki.fibis.org/index.php/Bengal_ArmyFifer ?, a Fifer is a musician who plays the fife ( flute ) in a marching band, a prety standard traditional instrument in military bands,...double check that word in case it might have been poorly legible and might have actually said Piper, bagpipes are still played in the Indian Army, of course it's not of any great significance though.
An Indian ?,...with a surname like Whiley, I doubt it, and presumably your marriage and birth records were British records and it's not hugely likely that an Indian of that time period would have had British nationality, and if the wedding was a Christian one, not very likely that an Indian of that time period would have been a Christian.
Military records of that era and location can be sparse and difficult to find, even if they exist, which many don't.
You aren't a huge fan of mentioning dates or ages, are you. ? :):)
Orphans ?, well that suggests that he and his wife died whilst their offspring were children, and there should be a record of his death, and likely so if he was serving in the HEIC Army in India when he died, that might have some additional info.
