Hi Tony regarding address's on the census.. if you click to go on the 71 for example.. scroll right down to counties.. click Lancashire... then click Liverpool.. then you get all the Wards in Liverpool... as Johnson St was in the Dale St Ward there are 24 districts in that ward..alone
I have the A-Z Edwardian Directory naming all the streets in Lpool.and there locations..... so i click district one to see whereabouts i am .. it names all the streets the emumerator has done in that district, so you keep going District 2 District 3 etc till you find Johnson St..
Its a bit time consuming but you get results..
The other way is to ask if anyone has the 1841,51.61 etc on CD.. they can go straight to the street for you.. i have the 1891 for all Lancs on Discs.
Belive it or not i found a woman on the 1891 the other day for someone.. this woman wasnt showing on the census at all.. we had Great Howard St as the address and a number.. this address was from a marriage cert late 1891.. Bingo there she was infact everyone on the page was not on the Ancestry census.. i searched for all of them and none showed up...
So there has to be loads of pages missing, i guess it depended on what state they were in.
Another lady said Roby St in Bootle was missing as she had a birth cert for the April 1891 and address was Roby St..the family cannot be found... yet they were still at the same address in 1901.
I have never found my husbands Gran and her parents on the 1891 or my own Great Gran and her parents.. so we could just be one of the unlucky ones i guess..
But 51,61,71 & 81 for your Thomas and Mary has to be too unlucky..
I still recon they are in Johnson St in Court 5 in 1871 even John Gannon is in the next street isnt he ..
I have asked a pal of mine to look at the electoral roll for you at the address's you gave for Peters Birth year and Mary Ann's marriage.. also Burlington St were Thomas Died..
Heres hoping he can help...
Chin up
