If my relative moved to Rockhaven in 1924, I was trying to look at the census of 1916 and 1921 to see if I could find anything on his cousin relatives. However, I found nothing for 1916 because I was able to narrow down the district and sub district that uncovered Rockhaven, then browsed though and found nothing. On the other hand for 1921 I'm wondering if the subdistrict is different. I'm having no luck coming up with Rockhaven. Although I realise there's still much I could learn on how to search.
