“Rothman family at their home in Skänninge, Sweden,” 1880s, by Carl Curman, via Swedish National Heritage Board Commons on flickr.
The photo shows Anders Nicolaus Rothman (who was town mayor) and his wife, Maria Charlotta (sister of the photographer), on the right. Their children are standing in the center. Notice the conch shells bordering the grass.

Brian Brake in the garden (looking a bit apprehensively at what I think is a cat), probably Wellington, New Zealand, 1927-1928, photographer unknown, via Museum of New Zealand/Te Papa Tongarewa.
Brian grew up to be an internationally recognized photojournalist.
“To uidentifiserte barn på en sti” (two unidentified children on a path), ca. 1910, place and photographer unknown, via Nasjonalbiblioteket/National Library of Norway.
“Portrait of well dressed small girl with pull-along horse,” Australia, ca. 1900, photographer unknown, via Phillips Glass Plate Negative Collection, Powerhouse Museum Commons on flickr.
The same little girl and her horse seem to appear in this photo as well. (And she’s in this one too.)
The artist Eppo Doeve painting the Martineau children at “Old Lodge in Terlow (Buckinghamshire),” Great Britain, July 1954, by Willem van de Poll, via Nationaal Archief (Netherlands).
I have not been able to find out anything about these siblings or the home. I cannot find an Old Lodge in Terlow, Buckinghamshire, or indeed a Terlow anywhere in Great Britain. The Martineau family is quite important in Birmingham (an ancestor of the Duchess of Cambridge was a Martineau), but apparently not in Buckinghamshire. Perhaps the photographer made some mistake in his notes.
The son on the right seems to have three golf balls between his fingers. A young amateur champion?
