Thread: what are thier correct names of the children?

Can anyone find a birth reg for the children of the following family.

I have Philip Kitchin b 1870 Millom, Cumberland who married Flora B. Lindley b 1878 Los Angeles County, California
Children:
US census California 1900 - Harry L Kitchin b 1898
US Census California 1910 - Harry L Kitchen 1898 Walter L Kitchen 1904
US census California 1920 - Henry Kitchin 1905 Harvey Kitchin 1898
US census California 1930 - Henry L Kitchin 1904

I am assuming that :
Walter L Kitchen 1904, Henry Kitchin 1905 & Henry L Kitchin 1904 are the same child.
and
Harry L Kitchin b 1898 & Harvey Kitchin 1898 are the same child.

The point is what are thier correct names ?

Thanks for the info Glojo21.

I found the obituary in the Los Angeles Times.
