Clugstons in Lehigh County, Pennsylvania

This may be James Cluxton 1816-, who emmigrated from Ireland to New York on the “Australia” 1854.
(Some information in this tree from findagrave)
I cannot find this family in the 1860 census, but it may be this family. But there is a James Clarkson 1819-1881 who died in Philadelphia.
This may be

James Clarkson 1821- b Ireland = Elizabeth Clarkson 1822- b Ireland
   (1860: Catasauqua, Lehigh, PA. Rebecca M Kensy 1795- b Ireland was staying with them)
    Eugenia 1849
    William 1851
    Rebecca 1853
    Mary 1855 

According to this link, one daughter of James and Elizabeth was
Rebecca Clugston 1852.12.15-1876.5.1 b PA = Henry Booth
