Robert Bovard family update

Yesterday I posted my findings about the Robert Bovard family. I realized last night that I had forgotten to add a county history to my research. I had found a Robert Bovard family in the book:
History of Dearborn, Ohio and Switzerland Counties, Indiana: From their earliest settlement, containing a history of the counties, their cities, townships, towns, villages, schools, and churches...biographies:...history of the North-west territory, the state of Indiana, and the Indians. 2 volumes. Chicago: Weakley, Harraman & Co., 1885.

The sketch of Robert Bovard is on page 1196:
"ROBERT BOVARD, farmer, Cotton Township, residing upon Section 28, was born in Dearborn County, Ind., May 10, 1825, and received a good common school education. His father, Robert Bovard, was born March 15, 1783; his mother, Margaret McGarvey, in Philadelphia August 16, 1788; his father was a farmer and boatman all his life: he used to keel a boat down the Mississippi River and back again. By his own industry and economy he made considerable property: he died May 12, 1854; Mrs. Bovard December 22, 1861. Their son, Robert, the subject of our sketch, has been a farmer all his life. He married March 4, 1858 to Miss Mariah Heath, who was born in Cotton Township October 22, 1830. By this union two children were born, viz: Lide, February 6, 1864, and Belle, August 18, 1867; is a member of Allensville Lodge No. 81, F. & A. M. and Beherald Chapter; he has officiated as W. M. of his lodge for about ten years, and is an industrious and useful citizen."

Now I have more information about the Bovard family:
Robert BOVARD was born 15 Mar 1783 in County Fermanagh, Ireland. He immigrated in 1803. He died 12 May 1854. Robert married Margaret MCGARVEY. Margaret was born 16 Aug 1788 in Philadelphia, Pennsylvania and died 22 Dec 1861.

You can see the family's migration across the United States from the birth places of their children. Robert was born in Ireland in 1783. At age 20, he immigrated to the U.S. He married Margeret MCGARVEY a few years later. Their two oldest children were born in Philadelphia. The next group of children was born in Ohio (possibly Hamilton county) and the youngest children were all born in Indiana (most likely Dearborn county).
