Hi Maris
I believe that Henry Harris was married to Charlotte Hinston on 30th Dec 1855 in Aston Juxta.
In 1891 census Henry was a Goods Guard from Hertfordshire born abt 1836, Charlotte, his wife, was born abt 1831. Their children at the time were Charlotte born 1866 and john born 1874.
Also as you are said above John Harris married Emily Keight 14th April 1898. (Marriage, ASTON, Warwickshire, April -June 1898, Vol 6d p 687)
His father was Henry Harris and hers was John Keight.
Emily Keight b.1876 Aston Warwickshire, july-sept Vol 6d p311
She was christened on the 31st August 1876 at St Andrew, Bordesley, Warwickshire.
Her parents were John Keight and Lydia.
In 1881 she was still at home with her parents at 46 Gt Barr Street, ASton. Strangley enough just down the road at the back on 95 (I think) were a Harris family.
1881 census:
Keight John Head M 34 1847 Coal Carter B'ham
Keight Lydia Wife F 26 1855 Aston, B'Ham
Keight Emily Daughter F 4 1877 Aston
Keight John Son M 2 1879 Aston

In 1901 John and Emily were living at 71 Bordelsey Green, Aston, Warwickshire

Harris Emily Wife F 24 1877

Harris Ernest son M 9 1902
Harris Lydia Daughter F 7 1904

I can't find the last two but the rest were christened at St James, Ashted, Birmingham
