The Holy Grail though is going to be finding a record of WHB's marriage to Helena which I could not find in the records for Bengal, Madras, Bombay, Ecclesiastical returns, or registrar records.
I am beginning to suspect that something fishy might have gone on, as Helena's first child was born in January 1881 and Helena was born in the first quarter 1864. Doing some simple maths shows that she would only have been a few weeks past her 16th birthday when..........
I suppose she could have married under-age, married as soon as she was 16, or married very quickly after getting a bit of a shock!
