Mack,
10175 Joseph Mullin 16th Bn, 6 Tudor St and J Mullins (no number) 16th Bn, 15 Worsley St, are both in the database but have no ICRC index cards, are they from your archives?
Two old entries
2769 Patrick Mullin 2nd Bn - no index card or further information.
9540 Munroe, no rank or forename, 2nd Bn - no index card, also 9540 is not as far as I can tell a Manchesters number.
Can you help with any of these.
Thanks
Charlie
