ROYE Family Tree - all related topics

Let's get this started - looking for information on the Royes esp. my grandparents (Dad/Private User's parents) & their ancestors:
- Names incl. parents, siblings, children, etc.
- Locations - birth place, place of death, etc.
- Dates - born, died, married, etc.
...would be a good start.

We know that Thatha (Dr. HSN Roye/Private) was born in Lahore (pre-Independence) but don't know much about his parents/family, even less about his wife/my paternal grandma (Private).

Dad (Private User) has some good info I'd like to add here.
