Born to Robert Graham , weaver - from 1899 d.c. No mother given. Almost certainly in Old Monkland, Lanarks
No sensible baptism on SP or on FS to a Robert Graham 1810-1815. All in Glasgow, not to east near Old Monkland. Maybe earlier? But there are baptisms 1813 & 1814 of an Agnes Graham in Paisley, both to John Grahams, one wife, Janet Cameron, the other Jean Cameron. Could Old Monkland be incorrect on all the census entries - or could there be 2 Old Monklands???
1829. Agnes Graham married Thomas Houstoun11/12/1829 in Renfrew SP & FS. Had mistakenly thought it was in Lochwinnoch- about 10 miles SW of Paisley.

1841C. Agnes Houston, 26, living Fulbar Street Renfrew with her husband, 4 children and his likely brother and mother, albeit given as Ellen rather than Mary, Houston.
| Thomas Houston | 30 | Cotton H L W | b. Renfrewshire . . . . actually 34/35 but age rounded down? |
| Agnes Houston | 26 | not b. Renfrewshire . .birth 1815 but then only 14/15 on marriage | |
| William Houston | 10 | b. Renfrewshire | |
| Agnes Houston | 8 | b. Renfrewshire | |
| Ellen Houston | 4 | b. Renfrewshire | |
| Alexander Houston | 2 | b. Renfrewshire | |
| Alexander Houston | 25 | Labourer | b. Renfrewshire. Probably a brother |
| Ellen Houston | 55 | Independent | not b. Renfrewshire Probably mother of Thomas |
1851C. Agnes Houston, 39, living in Pinkertons Lane, Renfrew with her husband and 4 children.
| Thomas Houston | 44 | HLW | b.Renfrew |
| Agnes Houston | 39 | b. Monkland, Lanarkshire . . ~15 E of Glasgow thus birth ~1812 | |
| Helen Houston | 16 | b.Renfrew | |
| Alexander Houston | 12 | b.Renfrew | |
| Robert Houston | 9 | b.Renfrew | |
| Thomas Houston | 3 | b.Renfrew |
1861C. Agnes Houston, 49, living Renfield Street, Renfrew, with her husband and 4 children.
| Thomas Houston | 55 | Labourer | b.Renfrew |
| Agnes Houston | 49 | b. Old Monkland, Lanarkshire thus birth ~1812 | |
| Thomas Houston | 13 | b.Renfrew | |
| John Houston | 9 | b.Renfrew | |
| Graham Houston | 7 | b.Renfrew | |
| Hannah Houston | 3 | b.Renfrew |
Thus they have given birth to children 1831-1858: this is feasible as Agnes was very young when she married in 1829.
1871C. Agnes Houston, 57, thus birth ~1814, married, wife of waterman, b. Old Monkland, Lanarkshire, is living at 21 Renfield Street, Renfrew, with daughter Hannah 13. So where is her husband? Also, on 12/12/1871, her granddaughter Helen Houston is born in Renfield Street - at Agnes's house??
1877. Her husband, Thomas Houston, labourer, 77, dies at 21 Renfield Street, Renfrew on 4/8/1877 of cancer of the stomach. Parents William Houston, weaver, & Ellen Wilson. Informant was his widow, Agnes Houston.
1881C. Agnes Houston, 69, thus birth ~1812, widow, b. Craigends, Lanarkshire is living alone at 21 Renfield Street . Craigends is ~8 miles NE of Lochwinnoch, near Houston - feel this just carelessly entered !
1891C. Agnes Houston, 79, widow is living at 21 Renfield Street, Renfrew, with 2 grandsons, sons of Alexander 1838.
| Agnes Houston | 79 | widow | b. Unknown |
| Hugh Houston | 17 | engineer | b.Renfrew |
| William Houston | 21 | engineer | b.Renfrew |
1899 Agnes Houston, 80, widow of Thomas Houston, labourer, dies 25/10/1899 at Renfield Street Renfrew of. Bronchitis. Father Robert Graham, weaver, deceased, no mother given. Informant Hannah Craignon, daughter. Age seems wrong!- birth 1819, impossible as she marries 1829! And her birth year from the censuses is ~1812
