My great-great grandfather lived in Buckinghamshire St from around 1875 (or earlier) and took care of his grandsons who became orphans when there were between 11 and 7 years old. My great-grandfather and his brother (two of the 3 orphans) lived in Brighton and in 1923 their brother visited from Australia. I have two photos from that visit and cannot place the locations. Grateful for any help on this. I will be in Brighton from 12 to 16 May 2024.
