The 2nd Jeremiah was the only son of Jeremiah and Jane. His baptism has not been found and while the ages in the various census records put him as born c. 1800 I think he was a bit younger - maybe 1806. I have what I believe is his marriage to Mary REES in Llanbister, Radnorshire on 16 Jun. 1826. Confirmation of this fact is in post #2. As for baptisms in or near Llanbister [based upon place of marriage] the only baptism I have found is for a Mary daughter of Thomas and Mary baptised [Non-Conformist] in Old Radnor on 11 Aug. 1805. After finding the couple with their 6 children in 1841 census [see post #1] I was led [via post #4] to investigate census records in the U.S. BINGO!!! 1850 - Big Rock, Kane, Illinois - Jeremiah [age 50 a Farmer], Mary [age 44] and 4 of his original 6 children [Jeremiah age 20, Elizabeth age 16, Sarah age 13 and Jacob age 9]. The only discrepancy was the birth place of Jacob. In addition to theses were John age 7 and Louisa age 4. Both were born in the U.S. - John c.1843 in Pennsylvania and Louisa c. 1846 in New York. 1860 - Big Rock, Kane, Illinois - Jeremiah [age 60 a Farmer], Mary [age 54], Jacob [age 19], John [age 17] and Louisa [age 13]. Both sons worked the farm with their father and Louisa was likely in school. 1870 - Big Rock, Kane, Illinois - Jeremiah [age 70 a Farmer] and Mary [age 64]. Also with them were 3 grandchildren [???] - Elizabeth [age 11], Jeremiah [age 7] and Ellen Mary [age 6] - all born Illinois. It would appear that Jeremiah owned the farm [value $ 9,400.00] and had personal property [value $1,880.00]. His next door neighbour was his son John along with Hattie his wife [age 22] and daughter Elizabeth [age 1]. I have now found a tree that I think accounts for Jeremiah and Mary - but need to review details further.
