I recently found the 1900 census that had eluded me by
having the family listed as McMullun.

In 1900 my family is listed as follows:

1900 Allegheney ward district 3 Pa
507 Ann Street
William James McMullan born March 25, 1875
immigrated from Antrin Ireland 1886
Married 6 years to Maggie (Smith) who immigrated
1894. 4 children 3 living.
daugh. Eliza J. born sept. 13, 1895
son William James Jr. born Feb. 3, 1896
son Archie born Mar. 1, 1898
MIL Eliza Smith widow 2 children 1 living bort, Jan 18, ???
she immigrated with Margaret 1894
__________________________________________________________

1910 I find them as

William J. McMillin est birth 1877 imm. Ireland 1883
Wife Margaret (Smith)immigrated 1893
William James Jr. birth 1896
Archiebald birth 1898
Mary M birth birth abt. 1901
Benjamin birt abt. 1901
Thomas Campbell birth Abt. 1905
Samuel Dempster birth abt. 1906
Eliza M. birth abt. 1909 (this child may have been
named after her older sister Eliza J. who died
Rosetta born abt. 1913
Eliza M.

so far this accounts for 10 children counting the death of one child unnamed in the 1900 census. This family had 14 children.

Looking for the other four. Family stories indicate two deceased. 12 lived of course Eliza J, may be one of the deceased.

By 1920 census the family is:

William James McMillen Sr.
Margaret McMillen
William James Jr.
Mary McMillen
Benjamin McMillen
Thomas McMillen
Samuel Dempster McMillen
Eliza M. McMillen
Rosetta McMillen

By 1930
the family is listed as consisting of
William James sr.
Margaret (maggie)
Benjamin
Rose Burkehart (I assume this is Rosetta married
Joseph Burkehart sil
Ann Martin McMillen dil

I am trying to find the other children, and the parents. siblings of William James Sr. Parents must have been
in pittsburgh as William Sr. would of been 6 years of age
at the time of immigration.
Anyone with these names in their families please contact me.
Thank You
