John Sedgwick  [parents unknown]
b. abt 1820, England
m. Elizabeth Unknown, England
immigrated to Indiana between 1845 - 1848

The only information I have about this Sedgwick Immigrant Ancestor is that he appears in these census records:

1850 INAllen, Lake Twp
1860 IN Allen, Wayne Twp
1870 IN Allen, Fort Wayne
Is that son John?
190 CA San Bernardino

The immigration date is deduced from the birthplaces of the children.
