I find it odd that a relatively prominent, affluent, family, particularly including photographers, would have such a blank photo album. One would expect photos of family, eg marriages, christenings, children, grandchildren, places visited on their travels and adventures. Photos with memorabilia like trophies, awards, group photos with club members, eg photographers club, rifle club, lodges, associations, regimental photos etc.
It may be worthwhile contacting members of the "Seale" family tree, which may help to confirm or eliminate this line. Walter and Kathleen Seale's death notices, burial records, headstone photos etc may include names of their children. There may have been articles in the Indian papers of family events, births, marriages, deaths.
