Is this a destitute Gidley family?

 Morning Post (London) 2 August 1821 

Two ladies and a child between 3 and 4 years old are desirous of becoming inmates of a genteel family within 20-50 miles of London. As their income is limited terms must be very moderate. Two bedrooms will be required. Address, post paid, to Mrs Gidley, 16 Queen Street, Brompton.

Morning Post 20 Oct 1821

To the affluent and benevolent. A Young Married Lady, under peculiar circumstances of distress and annoyance, drooping under oppression, and enduring with her infant the greatest privations, appeals to the Benevolent for the loan of £50 to be repaid at such periods as may be fixed upon within 12 months. The advertiser has a small independent income (though not at present available) which will enable her to reimburse the Lender with liberal interest. To the kind and feeling heart this appeal is made, to such a detail would be submitted as could not fail to interest those in whom power and inclination unite to befriend the unfortunate. Letters, post paid, to Mrs Gidley, Unwhyn's Library, No. 4 Catherine Street, Strand, will be gratefully acknowledged.

It's possible they are accommodation addresses or Gidley is even an assumed name. The details are too sparse to identify any likely candidates. Comments welcome!
