I am researching the descendants of Peter and Margaret (Haynes or Haines) Rankins who resided in Ohio.

Their Children...
E Rankins, Female, born around 1836 in Ohio
John Rankins, Male, born around 1838 in Ohio
Milton Rankins, Male, born around 1840 in Hamilton County, Ohio
William Rankins, Male, born around 1844 in Ohio
Sarah Rankins, Female, born around 1846 in Ohio
Martin Van Buren Rankins, male born May 1848 in Ohio

The family moved to Scioto County, Ohio just prior to 1850. Margaret Rankins and her children are listed on the Nile Twp census for 1850, but Peter is not in the household.

Milton Rankins married Martha Humble
Martin Van Buren Rankins married Martha Jane Leisure
The s was later dropped from the Rankins surname

In Milton Rankins bio for Pike County Ohio, Margaret's surname was spelled Haynes. Yet her household appears to be part of the "Haines" household on the 1850 census, family #175 in Nile TWP Scioto County. Her Mother Mary is also listed.
