I could be wrong, and am reluctant to be negative over this, but I cannot see a power that would allow a parish meeting to make donations to the poor. It seems to me that a parish council could do so under section 137 of the Local Government Act 1972 - the legislation that allows a parish council to spend (up to a certain limit) on anything that provides a clear benefit within the parish. But a parish meeting is not permitted to use this legislation.
