Hi Michael and Gadget (hope line problems are better!)
These are the children showing for the parents I posted earlier, from IGI. Mother Catherine's surname is Henderson, all actual extracts from the OPRs:
1. ALEXANDER BEAN Birth: 28 MAR 1843/ Christening: 16 APR 1843 Alloa, Clackmannan, Scotland
2. MARY BEAN Birth: 04 APR 1845/ Christening: 15 APR 1845 Alloa, Clackmannan, Scotland
3. JAMES BEAN Birth: 28 FEB 1847/ Christening: 14 MAR 1847 Alloa, Clackmannan, Scotland
4. JOHN MCLEOD BEAN Birth: 07 JUL 1850/ Christening: 21 JUL 1850 Alloa, Clackmannan, Scotland
5. WILLIAM BEAN Birth: 20 AUG 1855 Alloa, Clackmannan, Scotland
6. ISABELLA BEAN Christening: 13 JAN 1861 North Church, Dunfermline, Fife, Scotland
I hope it turns out to be the right family

If so, you have an 1855 birth cert. showing for William. The first year of official registration in Scotland and for one year only, the BMD entries ran over two pages of the registers. A wealth of additional info is included. For births it will tell you where the parents were from, ages, when they married, occupation of father, how many children they'd had (alive/deceased).....
Regards.

Gadget, was the occupation of the second father James also blacksmith?
