Hi, Eric!

Here is the household at 67 Duke Street, Onchan:

Frances E. White (Head) 49 Douglas Housekeeper
Edward G White Son Unmarried23 Corfu Mediterranean Stone Mason
Laurence A White Son Unmarried 21 b. Kerrucher, East Indies Stone Mason
Eliza A White Daur Female 15 Douglas Scholar
Robert H White Son 13 Douglas Scholar
Frances E White Daur 11 Douglas Scholar
Sarah M White Daur 7 Douglas Scholar

Here's one of the entries from Castle Rushen Gaol:

Lawrence White Prisoner Married 55 Kildare County Nase Town, Ireland Pensioner Private (Army) (b.~1826)

If you're interested in seeing who else was in gaol at the time, just look up Lawrence White and then 'view household' - it goes on for several pages, so be sure to hit next household. If you go forward from the prisoners, you'll get to the Military Barraks. Going back takes you to the Gaolers. Very interesting!
I suggest starting the search from the All Resources tab so that you can limit your search for Lawrence White to the Isle of Man. There are only 2.

Thanks for an intersting post!
Barbara
