Hi
The McAllum family are on the 1841 Northumberland census as Allum. Henry is shown as 7 years old
HO107/847/6 Folio: 49 Page: 55
I am copying this reply which I originally posted on Gereon's other McAllum post
Hi Gereon
I'm afraid your Henry McAllum is proving very elusive - despite the 1869 marriage
I can't find a Margaret McAllum and this is the only Mary I could find but given that one of her daughters is a widow, it suggests she is a lot older than Henry and as the marriage you found was 1869 - I doubt this is the right entry
Main St Corbridge - no ages or birthplaces shown and they are all shown as "Temporarily absent - visiting"
Mary McAllum widow
Mary - daughter
Eliza daughter
Elizabeth Beadle daughter widow
William Beadle grandson
Remember that website where I found Hugh & Ida's marriage - well here's Henry's. Looks like Mary was previously married. Venue unknown
1869 MCALLUM Henry
1869 CONWAY Mary B 1869 WALLACE Mary B
