We have a copy of a letter in Swedish to Claus Gustav Lind dated June 12, 1885, which includes "Farbror Christian och Amanda Lind häkar dig", which means "Uncle Christian and Amanda Lind greet you". So we conjecture that Christian and Amanda are uncle and aunt to Claus, and thus he is a brother of Carl August Lind. This letter is the only
vidence we have so far for these names.
