Thanks.
As your Francis was born in 1815, and mine Ca 1805, I don't think there is a connection. (or at least they are different Francis)
Francis' full family is
Francis Bell, b Canonbie Ca 1805 +/- 1 or 2 years d 1894 Merthyr Tydfil
m Agnes Graham b 1812 d 1864 Shrewsbury
Children:
1. Walter Bell, b. 20 Dec 1837, Thrumpton, Nottinghamshire
2. James Bell, b. 1839, Scotland
3. Francis Bell, b. 1840, Fulham, London d bef 1847
4. Margaret Bell, b. 1844, Fulham, London
5. George Bell, b. 1845, Scotland
6. Francis Bell, b. 1847, Scotland
7. Jane Bell, b. 1850, Grinshill, Shropshire
8. John Bell, b. 1853, Shawbury, Shropshire
I have so far been totally unable to find any details for the Scottish births
