More info. on Martin Brennan & Ann.  They lived in Stoke-on-Trent, Staffordshire.  1st son Patrick appears to have been born in Roscommon, Ireland.  So, I assume marriage also took place there also, as I cannot find a registered entry in England.

Children to the marriage: Patrick c.1859, John c. 1862 , Thomas c.1864, Ellen c.1865, Ann c.1867, Margaret b. 16/10/1868, Mary c.1870, all Burton Upon Trent, Katherine c.1873 & Mary Ann c.1878 both Longton, Stoke on Trent, Staffordshire.

Thanks for the offers of help.
