Lydia Jane Ferguson, b. 1822 PA, dau of David Ferguson

Looking for information about parents of Lydia Jane Ferguson, b. 1822 in Pennsylvania. Her death record states her father's name is David Ferguson, who (in census') was born in Ireland. Lydia married 1841 in Perry County, PA to Robert W. White. They settled in Warrick County, Indiana and raised a large family.
Any help would be appreciated.
