Pecks of Taita Nz

I have been concentrating my research on Samuel Peck 1875-1946
but he had 3 younger brothers and I would like information on them
if anyone knows anything

They were:
HENRY Peck b.1883 married Violet LAWRENCE d.1971

LEN (probably Leonard) Peck b.1886 married Ida NELSON

JACK Peck b.1889 d.1959 Apparently Jack did not marry
